Conditions

Temperature
50 °C

Procedure

A solution of 4-aminomethyl-2,3,4,9-tetrahydrothiopyrano[2,3-b]indole (1.0 g) in acetone (10 ml) is kept at room temperature for 30 minutes and then heated at 50° C. for 5 minutes. The solution is cooled with ice. The colorless precipitate is collected by filtration to give 4-isopropylideneaminomethyl-2,3,4,9-tetrahydrothiopyrano[2,3-b]indole (1.07 g) melting at 173° C. (decomp.).
