Reaction Steps

9.3 g (0.064 mol) of chloral were added dropwise to 10.4 g (0.05 mol) of 1-ethylcyclopentyl (1,2,4-triazol-1-yl)methyl ketone (prepared as described in Example 1) and 13.8 g (0.1 mol) of ground potassium carbonate in 100 ml of tetrahydrofuran. The reaction mixture was stirred overnight at room temperature and was then stirred with water. The solid formed was filtered off under suction and recrystallized from ethyl acetate. 7 g (39.5% of theory) of 1,1,1-trichloro-2-hydroxy-3-(1,2,4-triazol-1-yl)-4-(1-ethylcyclopentan-1-yl)-butan-4-one of melting point 194° to 196° C. were obtained.
