Triethylamine → 5-(4-(4-((6-(1H-Tetrazol-1-yl)pyridin-3-yloxy)methyl)-2H-1,2,3-triazol-2-yl)piperidin-1-ylsulfonyl)-2,4-dimethylthiazole

Participants

Reaction Steps

To a solution of 5-((2-(piperidin-4-yl)-2H-1,2,3-triazol-4-yl)methoxy)-2-(1H-tetrazol-1-yl)pyridine hydrochloride (Intermediate 15, 0.050 g, 0.153 mmol), dichloromethane (1.5 mL), and triethyl amine (0.043 mL, 0.306 mmol) was added 2,4-dimethyl-thiazole-5-sulfonyl chloride (0.049 g, 0.229 mmol) and the reaction stirred at room temperature for 2 hours. The solution was concentrated and purified by flash column chromatography on silica gel eluting with 0-100% ethyl acetate in hexanes to afford the desired product.
