1-Methyl-4-(methylamino)piperidine → HCID 68773722, compound

Participants

Reaction Steps

To a solution of 7-Bromo-1H-indole-3-carboxylic acid (A) (240 mg, 1 mmol) in dichloromethane (8 cm3) was added polystyrene-bound carbodiimide (1 g, loading 1.3 mmol/g, 1.3 mmol) followed by 1-methyl-4-(methylamino)piperidine (192 mg, 1.5 mmol) and the resulting suspension was gently shaken at room temperature for 16 h. The suspension was filtered and the resin washed with dichloromethane. The filtrate was then washed with saturated aqueous sodium bicarbonate solution, water before the organic portion was dried over magnesium sulfate, filtered and the filtrate evaporated under reduced pressure to give the title compound (B) (107.2 mg, 31%).
