Reaction Steps
5.0 g (14.07 mmol) methyl 3-(2-acetyl-4-benzyloxy-6-nitro-phenyl)-acrylate are combined with 100 mL ethanol and hydrogenated at 4 bar with Raney nickel as catalyst. The catalyst is separated off and the filtrate is acidified with 15 mL 2 N hydrochloric acid. The product that crystallises out is suction filtered and dried.
