实验步骤: A solution of 5-(N-Boc-amino)-5,7-dihydro-6H-dibenz[b,d]azepin-6-one (0.2 g, 0.617 mmol) (Example 7-E) in DMF was treated with Cs2CO3 (0.3 g, 0.925 mmol) and warmed to 60° C. To the reaction mixture was added 1-chloro-3,3-dimethyl-2-butanone (0.096 ml, 0.74 mmol) (Aldrich) and stirring continued for 17 h. After cooling to 23° C., the mixture was diluted with CH2Cl2, washed with several portions of brine and dried over Na2SO4. The title compound was isolated as a colorless solid. After cooling to 23° C. washed with several portions of brine dried over Na2SO4

实验步骤: A mixture of 4-{[3-(9-oxa-3,7-diazabicyclo[3.3.1]non-3-yl)propyl]amino}benzonitrile (Preparation C; 5.73 g, 0.02 mol), K2CO3 (11.05 g, 0.08 mol) in MeCN (300 mL) was treated with 1-chloropinacolone (4.44 g, 0.032 mol). The mixture was stirred at 50° C. overnight before DCM was added and the mixture filtered. The filter cake was then washed with a mixture of DCM and MeCN before the solvent was evaporated from the filtrate. The resulting residue was purified by chromatography on silica, eluting with a gradient of ethyl acetate:methanol:ammoniacal methanol (95:5:0 to 95:0:5), to give the title compound (5.8 g, 73.9%). was added the mixture filtered The filter cake was then washed with a mixture of DCM and MeCN before the solvent was evaporated from the filtrate The resulting residue was purified by chromatography on silica eluting with a gradient of ethyl acetate

实验步骤: A mixture of tert-butyl 9-oxa-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate hydrochloride (Preparation A; 0.26 g, 1.0 mmol) and K2CO3 (1.45 g, 10.5 mmol) in MeCN (8 mL) was treated with 1-chloropinacolone (0.216 g, 1.6 mmol), and the mixture stirred at 40° C. overnight. The following morning, the temperature was raised to 50° C. for 4 h before the solids were filtered off from the mixture and the filtrate concentrated in vacuo. The crude product was dissolved in DCM and the solution was added to an ion-exchange solid phase extraction plug (10 g CBA (carboxylic acid on silica support)). After 1 h, the plug was washed with DCM (15 mL), after which the product was finally eluted with dichloromethane:MeOH:TEA (90:5:5). The solvents were evaporated to give 0.276 g (85.5%) of the sub-title compound.

实验步骤: To a solution of 50 g of (R)-(−)-2-oxo-3-tert-butoxycarbonylamino-5-cyclohexyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine in 200 ml of dimethylsulfoxide were added 28.1 g of 1-chloropinacolone, 28.8 g of potassium carbonate (powder), 1.15 g of potassium iodide and 1.35 g of tetrabutylammonium bromide. The mixture was stirred at room temperature for 4 hours. The reaction mixture was poured into ice water. The precipitate thus formed was collected by filtration with suction, washed with water and then dried, whereby 63.5 g of the title compound was obtained. The precipitate thus formed was collected by filtration with suction washed with water dried

实验步骤: (1S)-1-(Hydroxymethyl)-3-methylbutylamine was made from (L)-leucine methyl ester as described in Method B1b. The 2-hydroxyethylamine was converted to (1S)-1-(chloromethyl)-3-methylbutanammonium chloride as described in Method B7a. 2-Methyl-4-nitrophenyl isothiocyanate was reacted with (1S)-1-(chloromethyl)-3-methylbutanammonium chloride according to Method C1a to give (4S)-2-(2-methyl-4-nitrophenylimino)-4-isobutyl-1,3-thiazolidine. The thiazolidine was reacted with 1-chloro-3,3-dimethyl-2-butanone according to Method D2a to afford (4S)-2-(2-methyl-4-nitrophenylimino)4-isobutyl-3-(2-oxo-3,3-dimethyl-1-butyl)-1,3-thiazolidine.
