Procedure

A mixture of 2-(4-fluoro-phenyl)-pyrimidine-5-carboxylic acid (107 mg, 0.49 mmol, prepared according to the general procedure described in Example 2, steps 1 and 2), 1-hydroxybenzotriazole (75 mg, 0.56 mmol) and PS-DCC (511 mg, 1.28 mmol/g, 0.65 mmol) in DMF (8 mL) is shaken at room temperature for 15 min. Aniline (30.4 mg, 0.33 mmol) is added. The mixture is shaken at room temperature for 18 hours. PS-trisamine (392 mg, 3.75 mmol/g, 1.47 mmol) is added and the mixture is continually shaken at room temperature for 18 hours. The solid is filtered and washed with EtOAc. The filtrate is concentrated to afford 2-(4-fluoro-phenyl)-pyrimidine-5-carboxylic acid phenylamide (83.4 mg, 86%) as a solid. MS: 294 (M+H).
