Reaction Steps

4-(5-Chloropyridin-2-yl)-1-(5-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-7-yl)pyridin-2(1H)-one (57 mg, 0.14 mmol) was reacted according to the procedure of Example 47 to provide the free-base. Conversion to the dihydrochloride salt using the procedure of Example 30 (step g) provided the title compound (54.5 mg, 81%) as a yellow solid: 1H NMR (500 MHz, CD3OD) δ 8.72 (d, J=1.7 Hz, 1H), 8.03 (d, J=7.9 Hz, 1H), 7.99 (dd, J=8.2, 2.2 Hz, 1H), 7.79 (d, J=7.1 Hz, 1H), 7.61 (d, J=8.3 Hz, 1H), 7.56 (d, J=1.3 Hz, 1H), 7.34 (d, J=1.5 Hz, 1H), 7.19 (dd, J=7.2, 1.8 Hz, 1H), 7.14 (dd, J=8.3, 1.8 Hz, 1H), 4.80-4.72 (br m, 1H), 4.46-4.34 (m, 1H), 3.96-3.86 (m, 1H), 3.75 (s, 3H), 3.65-3.55 (br m, 1H), 3.28 (s, 2H), 3.14 (s, 3H); ESI MS m/z 405 [M+H]+; HPLC (Method B)>99% (AUC), tR=12.0 min.
