Sodium hydride → HCID 49779446, compound

Participants

Reaction Steps

A flask was charged with sodium hydride (0.640 g, 50-60%) in dry DMF (10 mL) at 0° C. and to this was added 2,8-dimethyl-2,3,4,4a,5,9b-hexahydro-1H-pyrido[4,3-b]indole (0.8 g). The mixture was stirred at RT for 30 min. and then 4-(2-ethyloxiran-2-yl)pyridine (0.834 g) dissolved in DMF (2 mL) was added, stirred at RT for 12 h. The reaction mixture was diluted with ice-water and extracted with EtOAc (3×30 mL). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and evaporated. The crude product was triturated with diethyl ether to obtain the desired compound. 1H NMR (DMSO-d6, oxalate salt) δ (ppm): 8.45 (d, 2H), 7.42 (d, 2H), 7.30 (d, 1H), 7.10 (s, 1H), 6.82 (d, 1H), 4.30 (d, 1H), 4.18 (d, 1H), 3.60 (s, 2H), 3.50 (m, 2H), 3.38 (m, 1H), 3.0 (m, 2H), 2.90 (s, 3H), 3.32 (s, 3H), 2.10 (m, 1H), 0.6 (t, 3H).
