Procedure

3-Methoxy-2-methylbenzoic acid (5.0 g, 30 mmol) in CH2Cl2 (90 ml) and DMF (90 ml) was treated with HOBt (4.06 g, 30 mmol) and WSCDI (5.75 g, 30 mmol) and the resulting mixture stirred at RT for 20 min. After cooling to 0° C. ammonia (2H in EtOH, 30 ml, 60 mmol) was added and the mixture stirred for a further 2 h. The mixture was filtered, the solvent was removed from the filtrate. The crude material was taken up in CH2Cl2 and washed with water and brine and dried (Na2SO4), which gave a white solid (2.9 g) on isolation.
