실험 절차
A suspension of ethyl 4-(m-tolylcarbamoyl)piperazine-1-carboxylate (example 59, 1.5 g, 5.15 mmol) in dichloromethane (25 ml) was treated dropwise at room temperature with iodotrimethylsilane (1.6 ml, 11.3 mmol). The reaction mixture was stirred under nitrogen at room temperature overnight. The volatiles were evaporated to dryness, diluted with methanol and the solid was filtered off. The solid was washed with methanol and dichloromethane and dried under vacuum to yield the title compound as a yellow solid (1.1 g, 100%).
