Yield:-

Reaction Conditions:

with potassium carbonate in ISOPROPYLAMIDE; for 6 h;Heating / reflux;

Steps:

1.B

A mixture of 1A (1.89 g, 8.49 mmol) and potassium carbonate (3.5 g, 25.5 mmol) in dimethylacetamide (40 mL) was heated to reflux for 6 h. The reaction mixture was then concentrated in vacuo followed by the addition of water and saturated ammonium chloride. The solid product was collected by filtration with a water wash and then dried in vacuo to give the desired product 1B.
