Reaction Steps

To a solution of 9.7 g of 2-chloro-4-phenyl-6-methoxyquinazoline in 300 ml of ethanol were added 15 ml of hydrazine hydrate and 8 ml of glacial acetic acid and the mixture was refluxed for 5 hours. After the precipitate was filtered off, the filtrate was concentrated in vacuo to give crystals. The crystals were collected by filtration, washed with ethanol, and dried to give 7.8 g of 2-hydrazino-4-phenyl-6-methoxyquinazoline, a part of which was recrystallized from ethanol to give yellow scales, m.p. 151° - 152° C.
