Participants

Reaction Steps

To a solution of 6,7-dihydro-5H-pyrrolo[3,4-b]pyridine (5.00 g) in THF was added 80% NaH (3.00 g) at rt. The reaction mixture was stirred for 30 min at room temperature, and 5.3 mL of iodoethane was added dropwise. The reaction mixture was stirred for another 5 h, then quenched with ice water, and extracted with CH2Cl2 (70 mL×5). The combined organic phases were dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was chromatographed with a silica gel column (eluting agent: 30:1 (v/v) DCM/MeOH) to give the title compound as a pale yellow solid (2.80 g, 45.00%), HPLC: 90.00%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 149.3 (M+1); 1H NMR (400 MHz, d6-DMSO) δ: 1.02 (t, J=4.8 Hz, 3H), 2.64 (m, 2H), 3.62 (s, 2H), 3.95 (s, 2H), 7.11-7.83 (m, 3H) ppm.
