Reaction Steps

A mixture of 0.8 g of 3-[4-(3-Bromo-phenylamino)-quinazolin-6-ylamino]-4-ethoxy-cyclobut-3-ene-1,2-dione, 15 mL of 33 % methylamine, 5 mL of water, and 5 mL of ethanol was refluxed for 5 hr. The mixture was cooled to room temperature and the solid was collected and washed with ethanol and ether giving 0.45 g of 3-[4-(3-Bromo-phenylamino)-quinazolin-6-ylamino]-4-methylamino-cyclobut-3-ene-1,2-dione as a yellow powder: mass spectrum (m/e): M+H 426.0.
