실험 절차

A mixture of 1-(5-acetamido-2-chloro-4-fluorophenyl)-3-(2-propynyl)urea (4.50 g, 15.9 mmol), and pyridine (2.56 mL, 31.8 mmol) in methylene chloride is treated with N-(chlorocarbonyl) isocyanate (1.92 mL, 23.9 mmol), stirred at room temperature overnight, refluxed for 90 minutes, cooled to room temperature, treated with additional pyridine (1.30 mL) and N-(chlorocarbonyl) isocyanate (1.92 mL), stirred for 10 minutes, cooled to room temperature, and filtered to obtain a solid. The solid is washed sequentially with water and hexanes, and dried to give the title product as a tan solid.
