Reaction Conditions

Reaction Steps

To 5-methanesulfonyloxymethyl-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.50 g) is added a 30% solution of methylamine in methanol (50 ml), and the mixture is heated at 100° C. for 3 hours in a sealed tube. After cooling, the reaction solution is evaporated under reduced pressure, and the resulting residue is purified by silica gel column chromatography (eluent; dichloromethane:methanol:aqueous ammonia=100:10:1) to give 5-methylaminomethyl-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.07 g).
