5-Methylthiazole → 3-{3-[4-(3-Chloro-4-fluoro-phenylamino)-3-cyano-7-methoxy-quinolin-6-ylcarbamoyl]-allyl}-5-methyl-thiazol-3-ium bromide

Participants

Reaction Steps

A solution of 0.5 g (1 mmol) of 4-bromo-but-2-enoic acid[4-(3-chloro-4-fluoro-phenylamino)-3-cyano-7-methoxy-quinolin-6-yl]-amide and 0.6 g (6.1 mmol) of 5-methyl thiazole was refluxed for 4 hr. The mixture was diluted with ethyl acetate and cooled. Solid was collected and recrystallized from methanol-acetone-ethyl acetate to give 0.2 g of the title compound as a yellow powder: mass spectrum (electrospray, m/e): M+508.0, 509.9, (M+H)+2254.4, 255.1.
