Reaction Steps

The title compound of Example 149, step 3 was reacted with the title compound of Example 163, step 3 in a manner similar to Example 163, step 4 and the resulting 4-[5-(2,4-difluorophenoxy)-2-methylsulfonylpyrimidin-4-yl]-2-methyl-5,6,7,8-tetrahydroisoquinolin-1-one was treated with EtSO2NH2 instead of MeSO2NH2 in a manner similar to Example 163, step 5 to give the title compound. 1H NMR (DMSO-d6, 400 MHz): δ 8.38 (s, 1H), 7.61 (s, 1H), 7.35-7.31 (m, 1H), 7.04-6.95 (m, 2H), 3.41 (s, 3H), 3.30-3.20 (m, 2H), 2.42-2.40 (m, 2H), 2.32-2.30 (m, 2H), 1.61-1.51 (m, 4H), 1.18 (t, J=7.2 Hz, 3H). LCMS: 477.1 (M+H)+
