实验步骤: A stirred solution of N-(4-piperidylmethyl) 3,4-dihydro-2H-[1,3]oxazino[3,2-a]indole-10-carboxarnide (E21, 220 mg, 0.70 mmole) in acetonitrile (8 ml) was treated with diisopropylethylamine (0.24 ml, 1.4 mmole) and N-(2-bromoethyl)methanesulphonamide (D14, 160 mg, 0.77 mmole) and the mixture heated under reflux for 2.5 h. The reaction mixture was concentrated in vacuo and the residue chromatographed on silica gel eluting with dichloromethane/methanol/0.88 ammonia solution (200:10:1). The colourless oil obtained was dissolved in chloroform (30 ml) and washed with water (2×20 ml), then dried (Na2SO4) and concentrated in vacuo. The residue was passed through a short plug of basic alumina eluting with ethyl acetate to afford the title compound as a colourless oil (34 mg, 11%). This was converted to its oxalate salt and crystallised from acetone to give a white solid mp 80-85° C. the mixture heated under reflux for 2.5 h The reaction mixture was concentrated in vacuo the residue chromatographed on silica gel eluting with dichloromethane/methanol/0.88 ammonia solution (200:10:1) The colourless oil obtained washed with water (2×20 ml) dried (Na2SO4) concentrated in vacuo

实验步骤: To a solution of 8-((6-iodobenzo[d][1,3]dioxol-5-yl)thio)-9H-purin-6-amine (100 mg, 0.24 mmol) in 5 mL of dry DMF was added N-(2-bromoethyl)methanesulfonamide (150 mg, 0.7 mmol) and Cs2CO3 (150 mg, 0.46 mmol). The resulting mixture was stirred at a temperature of about 25° C. for 3 hrs, condensed under reduced pressure and purified by flash chromatography to provide compound WS35 as white solid (35 mg, 27% yield). condensed under reduced pressure purified by flash chromatography

实验步骤: 4-Piperidine methanol (1.60 g) was dissolved in dry acetonitrile (40 ml), N,N-diisopropylethylamine (5 ml) was added, followed by N-(2-bromoethyl)methanesulphonamide (2.95 g) in acetonitrile (10 ml), and the resulting mixture heated at reflux for 2 h. The solvent was removed in vacuo to leave a gum. This was purified by FCC eluting with System A (75:8:1) to give the title compound (1.80 g) as a solid, m.p. 81°-82°. the resulting mixture heated at reflux for 2 h The solvent was removed in vacuo to leave a gum This was purified by FCC eluting with System A (75:8:1)
