実験手順

To a solution of 5-((2H-1,2,3-triazol-4-yl)methoxy)-2-(1H-tetrazol-1-yl)pyridine (600 mg, 2.45 mmol), triphenylphosphine (1.5 eq.), and (2R,4S)—N-Boc-4-hydroxypiperidine-2-carboxylic acid methyl ester (1.5 eq.) dissolved in THF (20 mL) at 0° C. was added a solution of di-tertbutylazodicarboxylatc (1.5eq.) in THF (5 mL) drop wise. The reaction was allowed to warm to room temperature overnight and the solvents removed in vacuo The crude material was purified by flash column chromatography on silica gel to afford the desired product. 1H NMR (CDCl3): δ 9.44 (1H, s), 8.27 (1H, d), 8.03 (1H, d), 7.71 (1H, s), 7.58 (1H, dd), 5.27 (2H, s), 4.99-5.19 (1H, m), 4.57 (1H, m), 4.11-4.31 (1H, m), 3.79 (3H, s), 3.04-3.24 (1H, m), 2.75 (1H, m), 2.18-2.32 (2H, m), 2.05 (1H, m), 1.50 (9H, s). ES+-MS found: 486.1.
