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

实验步骤: Methanesulphonyl chloride (2.86 ml, 36.9 mmol) was added dropwise to an ice-cooled solution of 1-methoxy-2-propanol (3 ml, 30.7 mmol) and triethylamine (10.27 ml, 73.7 mmol) in dichloromethane (150 ml), and the reaction stirred at room temperature for 18 hours. The mixture was washed with water, then 2M hydrochloric acid, dried (MgSO4) and evaporated under reduced pressure to give the title compound as a yellow oil, 5.24 g. The mixture was washed with water 2M hydrochloric acid, dried (MgSO4) evaporated under reduced pressure

实验步骤: To a solution of 6-bromo-5-methyl-4H-pyrrolo[2,3-d]thiazole (2.5 g, 11.52 mmol) in anhydrous N,N-dimethylformamide (20 mL) was added 1-methoxypropan-2-yl methanesulfonate (3.87 g, 23.03 mmol), and potassium carbonate (3.18 g, 23.03 mmol) followed. The resulting reaction mixture was heated to 70° C. and allowed to stir over night at 70° C. The reaction mixture was washed with water and brine, extracted with acetic ester (30 mL×3). The combined organic phase was dried by anhydrous sodium sulphate, and then filtered. The filtrate was concentrated and purified by column chromatograph on silica gel eluted with (petrol ether/acetic ester 30:1→20:1→10:1) to the title compound (2.0 g, 60%) as orange oil. LCMS (M+H+) m/z: calc'd. 287.99. found 290.9. The resulting reaction mixture The reaction mixture was washed with water and brine extracted with acetic ester (30 mL×3) The combined organic phase was dried by anhydrous sodium sulphate filtered The filtrate was concentrated purified by column chromatograph on silica gel eluted with (petrol ether/acetic ester 30:1→20:1→10:1) to the title compound (2.0 g, 60%) as orange oil
