Reaction Steps

To a solution of 895 mg (6 mmol) of (+)-(6R)-(6,7-dihydro-5H-[1]pyrindin-6-yl)-methanol in 50 ml of anhydrous dichloromethane was added at −15° C. 0.918 ml (6.6 mmol) of triethylamine and 0.465 ml (6 mmol) of methanesulfonyl chloride. The resulting mixture was stirred at 0° C. for 45 min. The mixture was then diluted with water and dichloromethane and extracted with dichloromethane. Organic layer was dried and evaporated to give 1.4 g (100%) of methanesulfonic acid 6,7-dihydro-5H-[1]pyrindin-4-ylmethyl ester.
