Procedure

21.7 ml (160 mmol) of 4-methoxybenzyl chloride and 32.94 g (238 mmol) of potassium carbonate were added to a solution of 45.23 g (159 mmol) of the 2-hydroxy-N-methyl-1-(4-nitroimidazol-1-yl)cyclohexanecarbothioamide (L form) prepared in the Example 17 in 300 ml of N,N-dimethylformamide. The obtained mixture was stirred at room temperature for 17 hours to give a yellowish-brown suspension. Water and common salt were added to this suspension and the obtained mixture was extracted with ethyl acetate. The organic phase was washed with a saturated aqueous solution of common salt, dried over anhydrous magnesium sulfate, and concentrated in a vacuum. The obtained residue (65.5 g) was recrystallized from dichloromethane/ethyl acetate to give 42.78 g of the title compound as a light yellowish-brown crystal (yield: 66%).
