実験手順

The following was added sequentially to DMF (10 mL): 1-(4-fluorobenzyl)-1H-indole-2-carboxylic acid (1.175 g, 4.36 mmol), DIPEA (2.29 mL, 13.09 mmol), EDC (1.00 g, 5.24 mmol), and HOBT (802 mg, 5.24 mmol). This solution was allowed to stir at rt for 1.5 h, at which time 4-piperidinemethanol (754 mg, 6.55 mmol) was added. Stirring continued for 22 h at rt, at which time the solution was partitioned between water and 1:1 solution of ethyl acetate:diethyl ether. The organic extract was then washed with saturated aq. sodium carbonate, dried with magnesium sulfate, and concentrated in vacuo. Purification was accomplished via silica gel flash chromatography (100 g silica, 80% EtOAc/Hexanes.) Resulting residue was crystallized via diethyl ether/hexane trituration to give the title compound as a white solid. (Yield: 1.507 g, 4.11 mmol, 94%) 1H NMR (400 MHz, CDCl3) 7.63, 7.37, 7.28-7.22, 7.14, 7.08, 6.91, 6.60, 5.46, 4.65, 4.13, 3.42, 2.76, 1.76-1.54, 1.05, 0.71
