Procedure

Sodium hydride (275 mg, 11.45 mmol) was washed with hexane and dried under vacuum. DMF (4 mL) was added, resulting in a suspension. 2,3,4,5-Tetrahydro-2-methyl-8-chloro-1H-pyrido[4,3-b]indole (500 mg, 2.27 mmol) dissolved in DMF (2 mL) was added dropwise and the reaction mixture stirred for 30 min. at RT. 4-(2-Methyl-oxiranyl)-pyrimidine (620 mg, 4.55 mmol) dissolved in DMF (2 mL) was added dropwise and the reaction mixture was stirred overnight at RT. The progress of reaction was monitored by TLC. The mixture was quenched with ice-cold water and the mixture extracted with EtOAc (3×30 mL). The combined organic layer was washed with water (4×20 mL) followed by brine (1×20 mL), dried over sodium sulfate and the solvent evaporated under vacuum. The residue was washed with hexane and crystallized from ether:DCM and hexane. 1H NMR (CD3OD, oxalate salt) δ (ppm): 9.10 (s, 1H), 8.50 (d, 1H), 7.50 (d, 1H), 7.36 (s, 1H), 7.10 (d, 1H), 6.95 (d, 1H), 4.40 (m, 4H), 3.60 (m, 2H), 3.40 (m, 1H), 3.20 (m, 1H), 3.05 (s, 3H), 1.60 (s, 3H).
