Reaction Steps

Following Example 91, methyl 3-chloro-4-(8-cyano-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)benzoate was saponified with lithium hydroxide in THF and water, then the carboxylic acid was coupled with methylamine, HBTU, DIEA in dichloromethane to give 180. MS: (ESI+) 452.1
