Reaction Steps

To the solution of 3-(2-cyclohexyl-1H-imidazol-1-yl)-N-(2-ethoxyethyl)-4-nitrobenzamide as synthesized in above Production Example 48, 3.86 g in N,N-dimethylacetamide 32 mL, sodium hydride (formed by washing 60% sodium hydride, oiliness 600 mg with hexane) was added under cooling with ice. Then methyl iodide 1.55 mL was added and the ice bath was removed. After 1.8 hours' stirring, sodium hydride (formed by washing 60% sodium hydride, oiliness 200 mg with hexane) was added, followed by 5 hours' stirring. The reaction liquid was poured in water and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over magnesium sulfate. Distilling the solvent off, 3.35 g of the title compound was obtained.
