Mode opératoire

A mixture of 4-(4′-methylbiphenyl-2-carboxamido)-N-methyl-N-(2-hydroxymethylphenyl)benzamide (225 mg) and magnesium dioxide (651 mg) in chloroform (10 ml) was refluxed for 3 hours and the solution was filtered through Celite. The filtrate was evaporated in vacuo to give a crude oil and the oil was subjected to silica gel column (1% methanol in chloroform). The product was solidified with diethyl ether to give 4-(4′-methylbiphenyl-2-carboxamido)-N-methyl-N-(2-formylphenyl)benzamide (209 mg) as a white powder.
