Procedure

(±)-Cis-N-{1-[4-(2,5-dimethyl-pyrrol-1-yl)-benzoyl]-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl}-N-phenyl-propionamide was prepared from (±)-cis-N-[1-(4-amino-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-N-phenyl-propionamide. A solution of (±)-cis-N-[1-(4-amino-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-N-phenyl-propionamide (150 mg, 0.36 mmol), and propionic acid (0.5 ml) in dry benzene (20 ml) was heated at reflux under argon in a flask equipped with a Dean-Stark trap while stirring with the exclusion of light. The resulting solution was cooled to room temperature, and concentrated under vacuum. Recovered oil was purified by silica gel chromatography, eluting with hexane-ethyl acetate (3:1) to give the title compound (140 mg, 80%).
