Procedure

0.090 mL of pyridine and 0.12 mL of 2,6-dichlorobenzoyl chloride were added to 3.0 mL of toluene solution containing 0.15 g of tert-butyl 2-amino-4-phenylbenzoate at room temperature sequentially, and the resulting mixture was heated to reflux for 4 hours. The reaction mixture was cooled to room temperature and 0.023 mL of pyridine and 0.040 mL of 2,6-dichlorobenzoyl chloride were added sequentially and the resulting mixture was heated to reflux for 2 hours. The reaction mixture was cooled to room temperature and water was added. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium chloride aqueous solution, and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [Flash Tube 2008 manufactured by Trikonex Company, eluent; hexane:ethyl acetate=4:1] to obtain herb-butyl 2-(2,6-dichlorobenzamido)-4-phenylbenzoate.
