105 °C

Example 80 was prepared according to the general procedure in Example 2, except heating at 105° C. for 4 h followed by heating at 115° C. for 5.25 h, and using the following materials: Intermediate 1A (32.8 mg, 0.189 mmol), potassium carbonate (149.6 mg, 1.08 mmol), 4-methylpyrimidin-5-ylboronic acid hydrochloride salt (62.8 mg, 0.362 mmol), NMP (1.1 mL), deoxygenated water (100 μL), and PdCl2(dppf).CH2Cl2 (29.7 mg, 0.036 mmol). Example 80 was isolated as an off white solid (16.5 mg, 24.6%). Purification was done by preparative HPLC (Condition A) using a Phenomenex Luna Axia 30×100 mm S10 column from 5% Solvent B to 85% Solvent B over 12 min, ret. T=7.04 min, followed by purification by preparative HPLC (Condition B) using a Phenomenex Luna 30×100 mm S10 column from 15% Solvent B to 100% Solvent B over 12 min, ret. T=7.06 min. 1H NMR (500 MHz, METHANOL-d4) δ ppm 8.97-9.02 (1 H, m), 8.80 (1 H, d, J=4.58 Hz), 8.68 (1 H, ddd, J=8.09, 2.14, 1.07 Hz), 8.53-8.61 (2 H, m), 8.17 (1 H, s), 7.87-7.95 (1 H, m), 7.76 (1 H, t, J=7.93 Hz), 7.55 (1 H, d, J=5.19 Hz), 7.38 (1 H, d, J=4.58 Hz), 2.37 (3 H, s) LC/MS (Condition B): ret. T=2.20 min, (M+H)+ 366.01. Analytical HPLC: (Condition A): >98%, ret. T=18.43 min, (Condition B): >98%, ret. T=16.85 min, (Condition C): >97%, ret. T=5.64 min, (Condition D): >98%, ret. T=5.92 min.
