实验步骤: Methyl-[2-(2-{[1-methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carbonyl]-amino}-ethoxy)-ethyl]-carbamic acid tert-butyl ester (69 mg) was prepared by following General Procedure F starting from 1-methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carboxylic acid (82 mg), [2-(2-amino-ethoxy)-ethyl]-methyl-carbamic acid tert-butyl ester (87 mg), HBTU (91 mg), and DIEA (52 uL).

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: [2-(2-Amino-ethoxy)-ethyl]-methyl-carbamic acid tert-butyl ester (100 mg) was prepared following General Procedure T starting from [2-(2-dibenzylamino-ethoxy)-ethyl]-methyl-carbamic acid tert-butyl ester (200 mg) and Pd—C (40 mg) in methanol (1.5 mL).

实验步骤: A stirred solution of 4-chloro-3-nitroquinoline (32.3 g, 155 mmol) in 400 mL of anhydrous CH2Cl2, under N2, was treated with triethylamine (43.1 mL, 310 mmol) and tert-butyl 2-(2-aminoethoxy)ethyl(methyl)carbamate (37.2 g, 171 mmol). After stirring overnight, the reaction mixture was washed with H2O (2×300 mL) and brine (300 mL). The organic portion was dried over Na2SO4 and concentrated to give a brown oil. Column chromatography (SiO2, 33% ethyl acetate/hexanes-67% ethyl acetate/hexanes) gave 46.7 g of tert-butyl methyl(2-{2-[(3-nitroquinolin-4-yl)amino]ethoxy}ethyl)carbamate as a yellow solid. the reaction mixture was washed with H2O (2×300 mL) and brine (300 mL) The organic portion was dried over Na2SO4 concentrated to give a brown oil

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of tert-butyl 2-(2-azidoethoxy)ethyl(methyl)carbamate (41.9 g, 170 mmol) in 600 mL of MeOH was treated with 2.5 g of 10% Pd on carbon and shaken under H2 (3 Kg/cm2) for 24 h. The solution was then filtered through a Celite pad and concentrated to give 37.2 g of crude tert-butyl 2-(2-aminoethoxy)ethyl(methyl)carbamate as a light yellow liquid. The solution was then filtered through a Celite pad concentrated
