3-(dimethylamino)-2-methyl-1-phenylprop-2-en-1-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 57.0 g of propiophenone in 150 ml of N,N-dimethylformamide dimethyl acetal was stirred and heated at reflux for 24 hours. Then the solvent was removed in vacuo to give a yellow oil. The oil was subjected to Kugelrohr distillation to give 69.8 g of 3-dimethylamino-2-methylacrylophenone as a yellow oil, B.P. 100° C. (0.050 mm Hg). heated at reflux for 24 hours Then the solvent was removed in vacuo to give a yellow oil The oil was subjected to Kugelrohr distillation
