Reaction Conditions

Reaction Steps

1.25 g (0.0029×2.2 mol) of 3-(trifluoromethylthio) phenol was dissolved in about 10 ml of DMF. The obtained solution was further mixed with 0.23 g (ca. 60% in mineral oil; 0.0029×2.0 mol) of NaH and then with 0.80 g (0.0029 mol) of N-(i-propyl)-6-bromo-4-methoxy-2-pyridine carboxamide. After adding 0.15 g (0.0029×0.5 mol) of copper chloride (I), the obtained solution was stirred at about 110° C. for about 6 hours, and then allowed to stand for cooling to room temperature. After the reaction solution was distributed in ethyl acetate-saturated sodium bicarbonate water, the organic phase of the solution was washed with saturated brine and dried with anhydrous sodium sulfate, followed by concentration thereof. Thereafter, the concentrated solution was purified by silica gel column chromatography (eluting solution: ethyl acetate/hexane), thereby obtaining an aimed product.
