Reaction Steps

To a solution of 5-methoxy-3,4-dihydro-2H-pyrrole (520 mg) in MeOH (8 mL) was added (1S)-1H-inden-1-amine, 2,3-dihydro (538 mg, 4.04 mmol, CAS 61341-86-4) at room temperature. The mixture was stirred at room temperature for 40 h. The reaction was then cooled to room temperature and concentrated. Flash column chromatography (5% 7N NH3 in MeOH/DCM) yielded (S)—N-(2,3-dihydro-1H-inden-1-yl)-3,4-dihydro-2H-pyrrol-5-amine, as a white solid. 1H NMR (300 MHz, CDCl3) δ: 7.30-7.39 (m, 5H), 7.13-7.28 (m, 3H), 5.25-5.38 (m, 1H), 3.72 (t, J=6.7 Hz, 2H), 2.91-3.04 (m, 1H), 2.77-2.91 (m, 1H), 2.54-2.72 (m, 1H), 2.35-2.54 (m, 2H), 1.93-2.10 (m, 2H), 1.76-1.91 (m, 1H).
