Procedure

A mixture of 4-[6-(4-carboxymethyl-2-fluoro-phenoxy)-5-methyl-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (150 mg, 0.335 mmol) and HATU (178 mg, 0.469 mmol) in DMF (4 mL) was stirred for 30 minutes at room temperature. Then, dimethylamine (235 μL, 0.47 mmol) was added and the reaction was stirred for 24 hours at room temperature. The reaction was quenched with water and the product extracted in ethyl acetate. The organic layer was concentrated in vacuo and purified by HPLC to provide Compound C150 as a white solid (40 mg, 25%). 1H NMR (DMSO-d6, 400 MHz) δ 1.21 (d, 6H), 1.62-1.72 (m, 2H), 1.92-2.01 (m, 2H), 2.16 (s, 3H), 2.87 (s, 3H), 3.06 (s, 3H), 3.32-3.41 (m, 2H), 3.61-3.69 (m, 2H), 3.75 (s, 2H), 4.08 (h, 1H), 5.33 (h, 1H), 7.08 (d, 1H), 7.23-7.33 (m, 2H), 8.27 (s, 1H). Exact mass calculated for C24H31FN4O5 474.53, found 475.5 (MH+).
