Participants

Reaction Steps

A solution of 1-(7-tert-butyl-3,3-dimethyl-2,3-dihydrobenzo[b]furan-5-yl)-ethan-1-one (Example 2) (1.54 g, 6.25 mmol) in dimethylformamide dimethylacetal (15 mL) is heated at reflux for 17 h. The reaction mixture is evaporated, and the yellow residue is crystallized from hexanes to give 1-(7-tert-butyl-3,3-dimethyl-2,3-dihydrobenzo[b]furan-5-yl)-3-(N,N-dimethylamino)propen-1-one.
