Reaction Steps

To a solution of ethyl 2-chloro-4-methyl-7-(trifluoromethyl)-1,5-naphthyridine-3-carboxylate (0.97 g, 3.05 mmol, 1 eq.) in DMF (10 ml) were added K2CO3 (1.26 g, 9.15 mmol, 3 eq.) and ethanethiol (0.66 ml, 9.15 mmol, 3 eq.) at RT. The mixture was stirred at 60° C. for 16 h. Afterwards the mixture was diluted with water (80 ml) and was extracted with EtOAc (3×80 ml). The combined organic layers were washed with water (100 ml), brine (100 ml), dried over anhydrous Na2SO4 and evaporated to provide the crude product, which is purified by CC (EtOAc/hexane 1:9) to yield ethyl 2-(ethylthio)-4-methyl-7-(trifluoromethyl)-1,5-naphthyridine-3-carboxylate (0.75 g, 2.18 mmol, 71%).
