4-Methylmorpholine → HCID 9887722, compound

Participants

Reaction Steps

A solution of 0.43 g of 2-cyclopentenoic acid in 5 ml of tetrahydrofuran was cooled in an ice bath. A 0.49 ml portion of isobutyl chloroformate followed by a 0.41 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 10 ml of pyridine was added. The reaction was allowed to come to room temperature and stir overnight. Another 0.5 equivalents of mixed anhydride was added. The mixture was stirred for 5 hours. The solvents were removed at reduced pressure and the solid was purified by chromatography on silica gel to give 0.30 g of N-[4-[(3-bromophenyl)amino]-6-quinazolinyl]-2-cyclopenteneamide: mass spectrum (m/e): 409 (M+H, EI).
