반응 단계

To a solution of 3-((1H-1,2,3-triazol-5-yl)methoxy)-2-methylpyridine (0.20 g, 1.05 mmol), in THF (2 mL) at 0° C., was added 1-(5-(trifluoromethyl)pyrimidin-2-yl)piperidin-4-ol (0.391 g, 1.58 mmol) (Intermediate 20), polymer bound triphenylphosphine (0.527 g, 1.58 mmol), and di-tert-butylazodicarboxylate (0.363, 1.58 mmol). The reaction was allowed to warm to room temperature overnight and was then filtered through a pad of celite washing with THF. The solution was concentrated in vacuo and purified by flash column chromatography on silica gel eluting with 0-60% ethyl acetate in hexane to afford the desired product. 1H NMR (DMSO-d6): δ 8.71 (2H, s), 8.00 (1H, dd), 7.89 (1H, s), 7.47 (1H, dd), 7.19 (1H, dd), 5.18 (2H, s), 4.90 (1H, m), 4.68 (2H, s), 3.31 (2H, m), 2.31 (3H, s), 2.19 (2H, m), 1.92 (2H, m).
