Procedure

To a solution of 0.6 g (3.2 mmole) of 4-amino-5-chloro-2-methoxybenzoic acid in 15 ml of methylene chloride cooled to -15° C. was added 0.347 g (3.7 mmol) of ethyl chloroformate. The solution was stirred for 30 minutes and 1.0 g (3.2 mmole) of 1-methyl-4-(3-aminomethyl-5H-dibenzo[a,d]cycloheptene-5-ylidene)piperidine in 10 ml of methylene chloride was added. The solution was allowed to stir at room temperature for 2 hours. The solution was washed with 1N sodium hydroxide solution, water, and brine, and then was dried (MgSO4). After filtration, the solvent was removed under reduced pressure to give 4-amino-5-chloro-2-methoxy-N-((5-(l-methyl-4-piperidinylidene)-5H-dibenzo[a,d]cyclohepten-3-yl)methyl)benzamide as an amorphous foam.
