Reaction Steps

The mixture of 6.5 g of 7,7-diphenyl-hexahydro-1,4-oxazepine, 1.2 g of ethylene oxide, 0.5 ml of water and 20 ml of methanol is stirred at 40°-45° for 4 hours and at 50° for 21/2 hours. It is cooled, the precipitate formed, filtered off and recrystallized from benzene-hexane, to yield the 4-(2-hydroxyethyl)-7,7-diphenyl-hexahydro-1,4-oxazepine melting at 122°-123° (its hydrochloride melts at 190°-192°).
