Procedure
In an oven-dried, 50-mL, round-bottomed flask were placed 2-(4-pyridyl)-thiazole acetic acid (Step b, 140 mg, 0.64 mmol), 2-aminobenzaldehyde (Aldrich, 270 mg, 2.22 mmol), EDC (Aldrich, 244 mg, 1.27 mmol), and DIEA (Aldrich, 148 mg, 0.20 mL, 1.15 mmol) in CH2Cl2 (20 mL). The mixture was cooled to 0° C., and 1-hydroxy-7-azabenzotriazole (Aldrich, 173 mg, 1.27 mmol) was added in one portion. The reaction was warmed to RT slowly, stirred for 12 h, and concentrated in vacuo. The resulting crude product was purified by flash chromatography (EtOAc/hexanes, 50:50) to afford N-(2-formylphenyl)-2-(4-pyridyl)-thiazole acetamide as a white solid. Mp: 136-137° C. MS m/z: 324 (M+1). Calc'd for C17H13N3O2S: 323.07.
