Versuchsvorschrift

To a solution of oxalyl chloride (174 mg) in dichloromethane (15 ml) was added dimethyl sulfoxide (107 mg) at −78° C. and the solution was stirred at the same temperature for 10 minutes. A solution of 4-(4′-methylbiphenyl-2-carboxamido)-N-methyl-N-[2-(2-hydroxyethoxy)phenyl]benzamide (440 mg) in dichloromethane (5 ml) was added to the mixture at −78° C. After being stirred at −78° C. for 20 minutes, triethylamine (0.51 ml) was added to the mixture at the same temperature and the cooling bath was removed. The mixture was stirred at ambient temperature for 3 hours and the solution was washed successively with 1N hydrochloric acid, water and brine. The organic solution was dried over magnesium sulfate and the solvent was evaporated in vacuo to give 4-(4′-methylbiphenyl-2-carboxamido)-N-methyl-N-[2-(formylmethoxy)phenyl]benzamide (420 mg) as an amorphous.
