Procedure

6.8 g (0.04 mol) of the product from Example 12 are dissolved in 40 ml of 1 N sodium hydroxide solution and 5.56 g of S-methylisothiourea hydrogen sulfate (=0.04 mol of urea) in solid form are added. The mixture is stirred at room temperature for 24 hours, during which the product slowly crystallizes out, and is filtered off with suction and washed thoroughly with water. Yield: 2.8 g; melting point >297° C.
