Reaction Steps

8.4 g (70.6 mmol) of thionyl chloride was dropwise added to a solution of 10 g (61 mmol) of (isochroman-1-yl)methanol [J. Med. Chem., 28, 1026 (1985)] and 5 g (63 mmol) of anhydrous pyridine in dried benzene, and the resulting mixture was heated under reflux for 2 hours. Excessive amounts of thionyl chloride and benzene were evaporated, and the residue was dissolved in ether. The ethereal solution was washed with water and dried, and the solvent was then evaporated. The residue was distilled under reduced pressure (140° C./20 mmHg) to give 10.9 g (98%) of the desired compound as an oily.
