実験手順

In a 3-neck round bottom 100 mL flask was added toluene (8.5 mL), aqueous sodium carbonate (1.42 g in 10.7 mL water), and Intermediate 15 (0.905 mg, 4.26 mmol). The biphasic mixture was cooled to 0° C. After cooling to 0° C., 2-fluoro-6-[1,2,3]triazol-2-yl-benzoyl chloride was poured over the stirring biphasic mixture of amine and aqueous sodium carbonate. An exotherm was observed. The mixture was allowed to warm to room temperature. After 1 h, a sample of the organic layer was quenched into methanol and a small amount of acid chloride was determined to remain (observed as its methyl ester). Additional amine (˜50 mg) was added and the mixture was stirred overnight at room temperature. At the end of this period, the layers were separated and 100 mL of methanol were added to the organic layer. The organic was concentrated and purified using flash column chromatography (FCC), gradient of 5-50% of a solution of 10% MeOH, 0.1% NH4OH in DCM/DCM. The desired fractions were combined and concentrated to provide a white foamy solid (1.327 g, 76.8%). MS (ESI): mass calculated for C20H24FN5O3, 401.44, m/z found 346.2 [M+H-56]+. 1H NMR (400 MHz, CDCl3): 7.91-7.73 (m, 3H), 7.53-7.39 (m, 1H), 7.18-7.06 (m, 1H), 4.00-2.76 (m, 10H), 1.52-1.33 (m, 9H).
