실험 절차

30 g of 2,4-difluorophenyl(4-piperidinyl)methanone hydrochloride obtained in step B) and 30 g of hydroxylamine hydrochloride were added to 50 ml of ethanol. 29.5 ml of N,N-dimethylethanolamine was added thereto dropwise while stirring at room temperature, and then the mixture was refluxed for 3 hours. The reaction mixture was cooled to room temperature, and the precipitated solid was filtered and dried to obtain 26.4 g of the title compound as a white crystal (yield: 96%).
