反応手順
A solution of 3-chloro-1-propanol (1.88 g, 20 mmole) in 20 ml of pyridine was treated at 0° with tosyl chloride (7.6 g, 40 mmole). The solution was warmed to 23°, and stirred 16 hours. The reaction was diluted with 100 mL of H2O and stirred for 90 minutes, and extracted with Et2O. The extracts were washed with 1N HCl, dried, and the solvents thoroughly removed, and gave the titled product, 2.3 g (46%). MS (ESI) 188 (MH+).
