m-Chloroperbenzoic acid → HCID 22558451, compound

Participants

Reaction Steps

30 mg (0.1 mmol) of 60% 3-chloroperoxybenzoic acid were added to a stirred solution of 20 mg (0.051 mmol) of N-[3-methoxy-4-(5-oxazolyl)phenyl]-N′-[1,1-dimethyl-2-(4-pyridyl)ethyl]oxalamide in 1 ml of dichloromethane. The mixture was stirred for 1 hour then diluted with ethyl acetate, washed with sodium bisulphite solution, sodium bicarbonate solution and brine. The organic solution was dried over magnesium sulphate, evaporated to dryness and the residue triturated with diethyl ether to give 13 mg of N-[3-methoxy-4-(5-oxazolyl)phenyl]-N′-[1,1-dimethyl-2-(1-oxido-4-pyridyl)ethyl]oxalamide as an off-white solid. MS: m/e 411 [M+]+.
