Pyridine → N-allyltaurine isopropyl ester

2-Chloroethylsulfonyl chloride (2 g, 12.3 mmol) was is dissolved in 2-propanol (20 mL), pyridine (2.7 mL) was added, and the mixture was stirred at room temperature for 3 hours. Allylamine hydrochloride (1.15 g, 12.3 mmol) and diisopropylethylamine (6.4 mL) was added, and stirred at room temperature for 3 hours. The reaction mixture was evaporated under reduced pressure, 5% sodium bicarbonate solution was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the title compound (0.5 g, 2.4 mmol, 20%).
