Reaktionsschritte

A solution of 4 p-tolyloxy-acetic acid (60.1 mg, 0.36 mmol), 2-amino-isonicotinamide (74.1 mg, 0.54 mmol), DIPEA (0.12 ml, 0.72 mmol) and PyBOP (374.4 mg, 0.72 mmol) in DMF 5.0 mL was stirred, then partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over anhydrous MgSO4, and concentrated. The residue was purified by Prep-TLC(CH2Cl2:MeOH=10:1) to give 2-(2-p-tolyloxy-acetylamino)-isonicotinamide as a white solid (68.5 mg, 66.8% yield).
