Reaction Steps

N-(3,5-dichloropyrid-4-yl)-4-methoxy-8-amino-dibenzo[b,d]furan-1-carboxamide (100 mg, 0.249 mmol) (intermediate 1) was treated with acetyl chloride (22 mg, 0.299 mmol) in THF (10 ml) containing pyridine (23 mg, 0.299 mmol) at 0° C. and allowed to warm to room temperature. The reaction was stirred at room temperature for 30 min. THF was evaporated and the residue was washed with saturated sodium bicarbonate solution and water. The solid obtained was purified by silica gel column chromatography using 30% acetone-chloroform as eluent to obtain 25 mg of N-(3,5-dichloropyrid-4-yl)-4-methoxy-8-acetamido-dibenzo[b,d]furan-1-carboxamide as white solid; mp: 252° C.
