Reaction Steps

A mixture of 4-(2-chloroethyl)-1-methyl-4,5,6,7-tetrahydro-1H-indole (0.1 g, 0.5 mmol), N-methyl-N-benzylamine (0.07 g, 0.5 mmol), K2CO3 (0.20 g, 1.45 mmol) and a catalytic amount of NaI in DMF (5 mL) is heated to 110° C. overnight. The solvent is removed at reduced pressure, diethyl ether is added to the residue and washed with water. The organic phase is dried and evaporated at reduced pressure and the resulting crude is purified by column chromatography, giving N-benzyl-N-methyl-2-(1-methyl-4,5,6,7-tetrahydro-1H-indol-4-yl)ethanamine (0.04 g, 0.14 mmol, 28%, oil). (ESI-MS m/z 283 (M+H)+.
