Reaction Steps

1-(5-Methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-7-yl)-4-(5-(trifluoromethyl)pyridin-2-yl)pyridin-2(1H)-one (68 mg, 0.16 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 (39.6 mg, 48%) as a brown solid: mp 274-280° C.; 1H NMR (500 MHz, CD3OD) δ 9.04 (s, 1H), 8.28 (dd, J=8.7, 1.9 Hz, 1H), 8.21 (d, J=2.1 Hz, 1H), 7.83 (d, J=7.1 Hz, 1H), 7.62 (d, J=8.3 Hz, 1H), 7.58 (d, J=1.3 Hz, 1H), 7.39 (d, J=1.6 Hz, 1H), 7.24 (dd, J=7.1, 1.9 Hz, 1H), 7.15 (dd, J=8.3, 1.7 Hz, 1H), 4.80-4.71 (br m, 1H), 4.44-4.35 (br m, 1H), 3.96-3.86 (br m, 1H), 3.75 (s, 3H), 3.67-3.57 (br m, 1H), 3.28 (s, 2H), 3.14 (s, 3H); ESI MS m/z 439 [M+H]+; HPLC (Method B) 96.4% (AUC), tR=12.6 min.
