Versuchsvorschrift

Under an argon atmosphere, a suspension of methyl 4-(4-(4-(4-cyclohexylbenzyloxy)phenyl)-2-thiazolylaminomethyl)benzoate (65.0 g, 0.127 mol) obtained in Example 2(3) in N,N-dimethylformamide (130 ml) and dimethyl sulfate (15.0 ml, 0.159 mol) were successively added dropwise to a suspension of sodium hydride (content 60%, 6.09 g, 0.152 mol) in N,N-dimethylformamide (130 ml) at 10° C. or below and the mixture was stirred at room temperature for 1 hr. Diisopropyl ether (195 ml) and water (130 ml) were successively added dropwise at 10° C. or below, and the mixture was stirred at room temperature for 30 min. The precipitated crystals were collected by filtration, washed successively with diisopropyl ether (195 ml) and water (130 ml) and dried to give the title compound (56.0 g, 83.7%).
