With triethylamine; In dichloromethane; at 0℃; for 2.0h; | To a solution of 3-methanesulfonyl-propan-1-ol (Cambridge) (0.5 g, 3.6 mmol) in dichloromethane (3 mL) at 0 C. was added triethylamine (0.5 g, 5 mmol), and methanesulfonyl chloride (0.3 mL, 4 mmol, Aldrich). The reaction mixture was stirred at 0 C. for 2 h. The mixture was poured into water, extracted with dichloromethane. The organic layer was separated, washed with water, brine, dried over MgSO4, and concentrated to give crude methanesulfonic acid 3-methanesulfonyl-propyl ester as a yellow oil (Yield 0.7 g, 90%). | |
With triethylamine; In dichloromethane; at 30℃; for 12.0h; | To a solution of 3-methylsulfonylpropan-l-ol (200 mg, 1.45 mmol) in DCM (5 mL) was added Et3N (732 mg, 23.5 mmol) and methanesulfonyl chloride (2.84 g, 24.9 mmol). The mixture was stirred at 30 C for 12 hrs, and then partitioned between H20 (20 mL) and DCM (60 mL). The organic layer was separated, washed with brine (50 mL), dried over anhydrous Na2S04 and concentrated under reduced pressure to afford crude 3-methylsulfonylpropyl methane sulfonate (300 mg) as a yellow oil, which was used directly in the next step without further purification. | |
With triethylamine; In dichloromethane; at 20℃; for 1.0h; | The mixture of the compound 47 (0.100g), methanesulfonyl chloride (0.067 mL), triethylamine (0.120 mL), and a methylene chloride (2.0 mL) was stirred at the room temperature for 1 hour. Water was added to reaction mixed liquor and ethyl acetate extracted. The organic layer was concentrated in vacuum and the rough product of the title compound 48 was obtained. The whole quantity was then used to the next reaction. |
