A mixture of 4-[6-(4-bromo-2-fluoro-phenoxy)-5-methoxy-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (0.543 g, 1.21 mmol), sodium methane sulfinate (774.2 mg, 7.58 mmol), and N,N′-dimethyl-ethylene diamine (50.31 μL, 0.44 mmol) and copper (I) trifluoromethane sulfonate benzene complex (384.9 mg, 0.759 mmol) in 20 mL DMSO was heated in microwave for 7 minutes at 120° C. The mixture was purified by HPLC to give compound 4-[6-(2-fluoro-4-methanesulfonyl-phenoxy)-5-methoxy-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (Compound 76) as an oil (242.7 mg, 42%). 1HNMR (DMSO-d6, 400 MHz) δ 1.19-1.21 (d, 6H), 1.68-1.72 (m, 2H), 1.97-2.02 (m, 2H), 3.30-3.33 (m, 2H), 3.33 (s, 3H), 3.65-3.71 (m, 2H), 3.90 (s, 3H), 4.78-4.81 (m, 1H), 5.28-5.37 (m, 1H), 7.69-7.73 (m, 1H), 7.84-7.87 (m, 1H), 8.00-8.03 (m, 1H), 8.16 (s, 1H). Exact mass calculated for C21H26FN3O7S 483.15 found 484.2 (MH+).
