Participants

Reaction Steps

To a solution of 200 mg (0.63 mMol) of 4-benzylpiperidinyl-indole-2-carboxamide in 10 ml of acetone was added 321 mg (1.9 mMol) of 2-iodopropane and 106 mg (1.9 mMol) of powdered KOH. The mixture was refluxed for 3 h, then cooled, evaporated and the crude product was purified by silica gel column chromatography using EtOAc:hexane (1:4) to provide the 4-Benzylpiperidinyl-1-(2-propyl)-indole-2-carboxamide as white solids, NMR (DMSO-d6) δ=1.15 (m, 2H), 1.60 (d, 6H), 1.82 (m, 4H), 2.56 (d, 2H), 2.72 (m, 1H), 3.02 (m, 1H), 4.15 (m, 1H), 4.80 (m, 1H), 6.45 (s, 1H), 7.05-7.32 (m, 7H), 7.52 (d, 1H), 7.61 (d, 1H). MS (ESI) m/e 360 (M+).
