Participants

Reaction Steps

A suspension of N-(pyrid-4-yl)-4-methoxy dibenzo[b,d]furan-1-carboxamide (150 mg, 0.47 mmol) (example 3) and m-chloroperbenzoic acid (50-55%) (406 mg, 2.3 mmol) in chloroform (2.5 ml) was stirred at room temperature for 16 h. Chloroform was evaporated and the resulting solid was washed with saturated sodium bicarbonate solution, water, dried and then purified by column chromatography using 20% acetone-chloroform as the eluent to give 70 mg of N-pyrid-4-yl)-4-methoxy dibenzo[b,d]furan-1-carboxamide-N1-oxide as white solid; nip: 246-251° C.; IR (KBr): 3207, 3116, 3056, 2931, 2840, 2797, 1678, 1626, 1603, 1530, 1485, 1458, 1439, 1391, 1330, 1277, 1214, 1174, 1122, 1099, 1023, 851, 829, 791, 749 cm−1.
