3-Methyl-2-butenoyl chloride → HCID 9952643, compound

Participants

Reaction Steps

A solution of 1.58 g of N-(3-bromophenyl)-4,6-quinazolindiamine in 15 ml of pyridine was cooled in an ice bath and a solution of 0.67 ml of 3,3-dimethylacryloyl chloride in 7 ml of ether was added dropwise. After stirring and cooling for 2 hours, the solvents were removed at reduced pressure. The residue was treated with water and the resulting solid was recrystallized from methyl cellusolve to give 0.97 g of N-[4-[(3-bromophenyl)amino]-6-quinazolinyl]-3-methyl-2-butenamide: mp=300°-301° C., mass spectrum (m/e): 396, 398.
