Reaction Steps

To a solution of the title compound of step 7 (60 mg, 0.26 mmol), the title compound of Example 90, step 1 (111.2 mg, 0.32 mmol) and K2CO3 (107 mg, 0.78 mmol) in dioxane (4 mL) and water (1 mL) was added Pd(dppf)Cl2 (6 mg) under N2. The mixture was heated at 85° C. overnight. EA extractive work up followed by prep-TLC (DCM/MeOH=25:1) gave the title compound (47 mg, 48%) as a yellow solid. 1H NMR (DMSO-d6, 300 MHz): δ 7.83 (dd, J=8.7, 2.7 Hz, 1H), 7.66 (d, J=2.9 Hz, 1H), 7.58 (s, 1H), 7.25 (d, J=8.7 Hz, 1H), 3.95 (d, J=6.9 Hz, 2H), 3.46 (s, 3H), 3.17 (s, 3H), 2.65-2.70 (m, 4H), 1.91-1.97 (m, 2H), 1.13-1.18 (m, 1H), 0.50-0.54 (m, 2H), 0.26-0.30 (m, 2H). LCMS: 374 (M+1)+
