Acetone → HCID 21427785, compound

Participants

Reaction Steps

A solution of 15 g (0.1 mol) α,α-dimethyl-2-aminobenzyl alcohol and 5.7 g (0.1 mol) acetone in 120 ml of benzene was heated under reflux in a Dean-Stark trap for 3 hours. About 1.5 ml of water was separated from the reaction mixture. The benzene solution was then evaporated to give an oil which solidified on standing. Recrystallization from ethanol-water gave 5.2 g 2,2,4,4-tetramethyl-1,2-dihydro-4H-3,1-benzoxazine, as a white solid.
