Ammonia → HCID 231006, compound

Participants

Reaction Steps

44.5 ml (351 mmol) oxalyl chloride was added dropwise at 0° C. within 45 min. to a suspension of 50.0 g (281 mmol) 3-(4-Methoxyphenyl)-acrylic acid in 300 ml tetrahydrofuran and 3.0 ml N,N-dimethyl formamide. Stirring was continued at 0–5° C. for 30 min. and thereafter for 2 h at room temperature. The resulting solution was cooled to 0–5° C. again and then added within 15 min. to 750 ml of a 25% aqueous solution of ammonia. After stirring for 30 min. the precipitated amide was collected, washed with water and dried at 40° C. in vacuo. 48.8 g (98%) 3-(4-Methoxyphenyl)-acrylamide were obtained.
