Participants

Reaction Steps

Triethylamine (1.24 mL, 8.87 mmol) and isobutyl chloroformate (0.50 mL, 3.9 mmol) are added to 1-methoxy-4-bromo-2-naphthoic acid (European Published Patent Application EP 0 539 281A1) (1.0 g, 3.55 mmol) in dry tetrahydrofuran (20 mL) at 0° C. and allowed to stir for 1 hour. To this mixed anhydride is added 4-(2,3-dichlorophenyl)-l-piperazineethanamine (0.97 g, 3.55 mmol) in dry tetrahydrofuran (5 mL) and stirring continued for 18 hours, gradually allowing the mixture to warm to room temperature. The reaction mixture is washed with saturated sodium chloride (NaCl), dried (sodium sulfate), and concentrated to give 0.27 g of the title compound as a white solid; mp 137° C.
