HCID 118022276US10023592, Example 157

Procedure

The title compound of Example 47, step 2 was treated with 4,4,5,5-tetramethyl-2-(tetramethyl-1,3,2-dioxaborolan-2-yl)-1,3,2-dioxaborolane in a manner similar to Example 89, step 1 and the resulting 6-fluoro-2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoquinolin-1-one was coupled to the title compound of Example 152, step 4 in a manner similar to Example 152, step 5 and the resulting 4-[5-(cyclopropylmethoxy)-2-methylsulfonylpyrimidin-4-yl]-6-fluoro-2-methylisoquinolin-1-one was treated with EtSO2NH2 instead of MeSO2NH2 in a manner similar to Example 152, step 6 to give the title compound. 1H NMR (DMSO-d6, 400 MHz) δ 11.04 (brs, 1H), 8.54 (s, 1H), 8.36 (dd, J1=9.2 Hz, J2=2.4 Hz, 1H), 8.01 (s, 1H), 7.65 (dd, J1=11.2 Hz, J2=2.4 Hz, 1H), 7.45-7.38 (m, 1H), 3.95 (d, J=6.8 Hz, 2H), 3.58 (s, 3H), 3.48 (q, J=7.2 Hz, 2H), 1.22 (t, J=7.2 Hz, 3H), 1.16-1.04 (m, 1H), 0.50-0.42 (m, 2H), 0.27-0.20 (m, 2H).
