実験手順
7 ml of a 37% strength solution of formaldehyde in water were added to 1000 mg (4.24 mmol) of 5-(4-chlorophenyl)-4-cyclopropyl-2,4-dihydro-3H-1,2,4-triazol-3-one [preparation according to WO 2007/134862 Example 36A], and the mixture was stirred at RT for 20 h. The precipitated solid was filtered off with suction and washed with water. Drying under high vacuum gave 878 mg (62% of theory) of the target compound.
