Thiomorpholin-3-one (11.7 g, 0.1 mol) was added in portions over 30 minutes with stirring. After gas evolution had stopped (ca. 30 minutes), benzyl chloride (12.1 g, 0.105 mol) in DMF (50 mL) was added and stirring was continued at room temperature overnight. The reaction was then warmed to 80 C. for 15 minutes and cooled. Water (250 mL) was added and the mixture was extracted with chloroform which was dried (MgSO4) and concentrated in vacuo to an oil. The oil was triturated with ethyl ether (Et2O) and cooled by dry ice to give the product, 12.75 g as a solid, m.p. 60-42 C. Recrystallization of 5 g from 100 mL of Et2O gave 3.5 g of pure product, m.p. 62-43 C. along with a second crop of 0.75 g with m.p. 62-43 C.
