Versuchsvorschrift

N1-phenyl-4-methoxy-8-amino-dibenzo[b,d]furan-1-carboxamide (69 mg, 0.207 mmol) (step 2) was treated with acetyl chloride (1.1 eq.) in THF (10 ml) containing pyridine (1.1 eq) at 0° C. and allowed to warm to room temperature. The reaction was stirred at room temperature for 2 h. THF was evaporated and the residue was washed ethanol to obtain 40 mg of N1-phenyl-4-methoxy-8-acetamido-dibenzo[b,d]furan-1-carboxamide as white solid; mp: 252° C.
