Procedure

(S)-3-Hydroxymethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (0.65 mmol, 131 mg) and sodium hydride (1.3 mmol, 31 mg) were dissolved in N,N-dimethyl acetamide (1.5 mL) and stirred for 30 minutes at room temperature. Then, (6-chloro-5-nitro-pyrimidin-4-yl)-(4-methanesulfonyl-phenyl)-amine (0.26 mmol, 84 mg) was added. The reaction was stirred at 70° C. for 30 minutes. Its progress was monitored by thin layer chromatography and LCMS. Sodium hydride was quenched with water and the desired compound was extracted in ethyl acetate. Organic solvents were evaporated in vacuo. Flash chromatography (Silica gel 60; 50/50 EtoAc/Hexanes) provided Compound A17 as a yellow solid (26 mg, 15%). 1H NMR (400 MHz, CDCl3) δ (ppm): 10.22 (s, 1H), 8.41 (s, 1H), 7.97 (d, 2H), 7.87 (d, 2H), 4.52 (m, 2H), 3.49 (m, 2H), 3.09 (s, 3H), 2.75 (m, 1H), 1.97 (m, 2H), 1.67 (m, 2H), 1.49 (s, 9H). LCMS (ESI), m/z 394.1 (M+H+, 100%).
