Reaction Steps

Pyridine (5 mL) was added to a mixture of 3-amino-4-methoxy-N-phenyl-benzamide (0.73 g, 3.0 mmol) and dansyl chloride (0.81 g, 3.0 mmol) and stirred under an inert atmosphere at room temperature. After 20 hours, the mixture was diluted with water (50 mL) and extracted with ethyl acetate (2×50 mL). The combined extracts were washed with water then saturated brine, then dried over MgSO4 and stripped of solvent under reduced pressure to afford the product (1.3 g); m.p. 231-232° C.
