Hydrochloric Acid → HCID 5329079, compound

Participants

Reaction Steps

A 2.5 ml portion of 10 N aqueous sodium hydroxide was added to 2.3 g of 4-[[4-[(3-bromophenyl)amino]-6-quinazolinyl]amino]-4oxo-(E)-2-butenoic acid ethyl ester (Example 5) in 25 ml of ethanol. After stirring for an hour, 2.1 ml of concentrated hydrochloric acid was added, and the reaction was stirred an additional 2 hours. The resulting solid was recrystallized from n-butanol to give 0.97 g of 4-[[4-[(3-Bromophenyl)amino]-6-quinazolinyl]amino]-4-oxo-(E)-2-butenoic acid: mass spectrum (m/e): M+H 413.
