Reaction Steps

To a solution of 2-(2-isopropylphenyl)imino-5,5-dimethyl-1,3-thiazine (0.26 g), 5-trifluoromethyl-2-chloropyridine (0.24 g) in N,N-dimethylformamide (3 ml) was added 60% sodium hydride (0.05 g) under ice-cooling. The mixture was stirred at room temperature for 2 h. To a reaction mixture was added water (80 ml), extracted with diethylether (100 ml), dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-hexane/ethyl acetate) to give 2-(2-isopropylphenyl)imino-3-(5-trifluoromethyl-2-pyridyl)-5,5-dimethyl-1,3-thiazine (0.13 g, yield: 32%) as colorless oil.
