Pyridine → 3-ethoxy-N-(4-iodo-phenyl)-acrylamide

Participants

Reaction Steps

To the mixture of 4-iodoaniline (14 g, 64 mmol) and pyridine (10.5 mL, 128 mmol) in methylene chloride (85 mL) was added 3-ethoxy-acryloyl chloride (10 g, 75 mmol). After stirring for 5 hrs, more 3-ethoxy-acryloyl chloride (5 g, 38 mmol) and pyridine (10.5 mL, 64 mmol) was added. After stirring for 2 days, the reaction mixture was washed with water 3×100 mL), dried over MgSO4 and concentrated to give 3-ethoxy-N-(4-iodo-phenyl)-acrylamide as black oil (11.32 g, 56%). LC-MS m/e 318 (MH+).
