The mixture was stirred at room temperature for 30 min. Next, 2,4-difluorobenzylamine (28 μl) was added to the reaction solution, and the mixture was further stirred at room temperature overnight. The precipitated crystal was collected by filtration and was washed to give 20 mg (yield 26%) of the title compound.
