Reaction Steps

1-(5-Methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-7-yl)-4-(pyridin-2-ylmethoxy)pyridin-2(1H)-one (45 mg, 0.116 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 mg, 98%) as a white solid: mp 260-265° C.; 1H NMR (500 MHz, CD3OD) δ 8.87 (d, J=5.7 Hz, 1H), 8.58 (overlapping dd, J=8.2 Hz, 1H), 8.14 (d, J=7.9 Hz, 1H), 8.00 (overlapping dd, J=6.6 Hz, 1H), 7.69 (d, J=7.6 Hz, 1H), 7.59 (d, J=8.3 Hz, 1H), 7.49 (s, 1H), 7.07 (dd, J=8.3, 1.7 Hz, 1H), 6.44 (dd, J=7.5, 2.6 Hz, 1H), 6.20 (d, J=2.0 Hz, 1H), 5.56 (s, 2H), 4.76 (d, J=14.2 Hz, 1H), 4.40 (d, J=14.2 Hz, 1H), 3.91 (m, 1H), 3.74 (s, 3H), 3.61 (m, 1H), 3.29-3.17 (m overlapping with solvent, 2H), 3.13 (s, 3H); ESI MS m/z 401 [M+H]+; HPLC (Method B)>99% (AUC), tR=9.2 min.
