Procedure

Methanesulfonic acid-4-(2,8-dimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-3-pyridin-4-yl-butyl ester (200 mg, 0.468 mmol) in 10 mL of 40% aqueous dimethyl amine was heated at 100° C. for 1 h. The progress of reaction was monitored by TLC. After consumption of starting material, the reaction mixture was dried and the crude product was purified by reverse phase chromatography to obtain 170 mg of [4-(2,8-dimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-3-pyridin-4-yl-butyl]-dimethyl-amine as the TFA salt. 1H NMR (CD3OD, TFA salt) δ (ppm): 8.57 b (s, 2H), 7.65 (dd, 2H), 7.23 (d, 1H), 7.21 (s, 1H), 6.99 (d, 1H), 4.62 (m, 1H), 4.48 (m, 1H), 4.42 (m, 1H), 4.26 (t, 1H), 3.81 (m, 1H), 3.55 (m, 2H), 3.35 (m, 1H), 3.1 (m, 1H), 3.0 (s, 3H), 2.9 (m, 2H), 2.83 (s, 6H), 2.4 (m, 1H), 2.38 (s, 3H), 2.29 (m, 1H). Separation by chiral HPLC provides enantiomers II-232a-b.
