Reaction Steps

Mixture of (R)-2-chloro-1-(2-methyl-2-oxiranylmethyl)-4-nitroimidazole (2.50 g, 11.5 mM) obtained in example 7 and 4-(4-trifluoromethoxyphenyl)piperazine (3.11 g, 12.6 mM) in N,N-dimethylformamide (25 ml) was stirred at 70° C. for 7 hours. The temperature of reaction mixture was turned back to a room temperature, water was added and extracted twice with ethyl acetate. The organic layers were combined, washed with water three times, dried on anhydrous magnesium sulfate and filtered. The filtrate was concentrated under a reduced pressure, there was obtained (S)-1-(2-chloro-4-nitroimidazol-1-yl)-2-methyl-3-[4-(4-trifluoromethoxyphenyl)piperazin-1-yl]propan-2-ol (5.55 g, yield: 100%) of slightly yellow oily product.
