実験手順

To a mixture of (5-methyl-2-phenyl-4-thiazolyl)methanol (5.0 g), 6-chloro-3-cyanopyridine (3.38 g) and N,N-dimethylformamide (100 mL) was added sodium hydride (60%, oil, 1.07 g) under ice-cooling. The reaction mixture was stirred at room temperature for 1 hr. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated. The obtained residue was subjected to silica gel column chromatography to give crystals (5.55 g, 74%) of 6-[(5-methyl-2-phenyl-4-thiazolyl)methoxy]nicotinonitrile from a fraction eluted with ethyl acetate-hexane (1:2, v/v). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 124-125° C.
