4-Methylmorpholine → N-[4-[(3-bromophenyl)amino]-6-quinazolinyl]-(3-phenyl-2-propynamide)

Participants

Reaction Steps

A solution of 0.93 g of 3-phenyl-2-propynoic acid in 10 ml of tetrahydrofuran was cooled in an ice bath. A 0.82 ml portion of isobutyl chloroformate followed by a 0.69 ml portion of N-methyl morpholine were added. After about 1 minute a solution of 1.0 g of N-(3-bromophenyl)4,6-quinazolindiamine in 7 ml of pyridine was added. The reaction at 0° C. for 1 hr.. The solvents were removed at reduced pressure and the solid was purified by chromatography on silica gel to give 0.01 g of N-[4-[(3-bromophenyl)amino]-6-quinazolinyl]-(3-phenyl-2-propynamide): mass spectrum (m/e): 443.2, 445.2 (M+H, electrospray).
