实验步骤: 5-Phenylmethylthio-7-chloro-thiazolo[4,5-d]pyrimidin-2-ylamin (100 mg, 0.32 mmol), DL-2-amino-1-hexanol (295 μL, 2.3 mmol) and potassium carbonate (124 mg, 0.90 mmol) were heated for 24 hours as in Example 1. The solution was filtered and the solvent was evaporated. The crude product was flash chromatographed on silica (gradient eluent—ammonia:ethylacetate:dichloromethane, 1:69:30 to 1:99:0) resulting in 22 mg (17% yield) of the title compound as a yellow solid. The solution was filtered the solvent was evaporated chromatographed on silica (gradient eluent—ammonia:ethylacetate:dichloromethane, 1:69:30 to 1:99:0)

反应条件: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a stirred cold solution of DL-2-amino-1-hexanol (1.1 ml) in dry THF (10 ml) was added triethylamine (2.8 ml) followed by dropwise addition of thiophosgene (0.81 ml) in dry THF (9 ml). The mixture was then stirred for 18 h at 20° C., evaporated under reduced pressure and the residue partitioned between water and diethyl ether. The ether extract was dried with sodium sulphate filtered and evaporated. The residue was dissolved in the minimum of hot 1:1 dimethylether-hexane and crystallised on cooling to give 4-butyloxazolidine-2-thione, mp 71-2°. evaporated under reduced pressure the residue partitioned between water and diethyl ether The ether extract was dried with sodium sulphate filtered evaporated The residue was dissolved in the minimum of hot 1:1 dimethylether-hexane crystallised on cooling
