Procedure

19.56 g (116 mmol) of (2-methylphneyl)acetic acid chloride are added, over 1 hour, to a mixture of 20 g (116 mmol) of 4-amino-2-chlorobenzoic acid, 12.9 g (127 mmol) of triethylamine and 150 ml of DMF dried over a molecular sieve. After stirring for 16 h at room temperature, the DMF is removed by evaporation under vacuum. The residue is washed with water and with dichloromethane to give, after drying, 19 g of an off-white powder (Yield=53%).
