Sodium hydride → HCID 49779376, compound

Participants

Reaction Steps

To a solution of 2,3,8-trimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (500 mg, 2.3 mmol) in DMF (10 mL) was added sodium hydride (276 mg, 6.9 mmol). After stirring for 10 min at RT, 4-(2-methyl-oxiranyl)-pyridine (473 mg, 3.5 mmol) was added and stirring continued for another 16 h. The reaction mixture was poured into ice water and extracted with EtOAc. The organic layer was washed with water, dried over sodium sulfate and concentrated to afford crude material, which was re-crystallized in ether-hexane to yield 2-(pyridin-4-yl)-1-(2,3,8-trimethyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)propan-2-ol. 1H NMR (DMSO, HCl salt) d (ppm): 8.62 (d, 2H), 8.10 (d, 2H), 7.18 (s, 1H), 6.90 (m, 1H), 6.80 (m, 1H), 4.62 (m, 2H), 4.40 (m, 3H), 4.05 (m, 1H), 3.80 (m, 1H), 3.05 (s, 3H), 2.38 (s, 3H), 1.75 (d, 3H), 1.70-1.50 (m, 3H).
