4-Methoxycarbonylmethyl-benzoic acid (52.00 mg, 0.27 mmol) was suspended in dichloromethane (2.00 mL) and treated with thionyl chloride (95.57 mg, 0.80 mmol). The mixture was stirred at 50° C. for 18 hours, and the volatiles were evaporated. The residue was redissolved in tetrahydrofuran (2.00 mL) and treated with 1-(5-chloro-2-methoxy-benzenesulfonyl)-1,2,3,4-tetrahydro-quinolin-7-ylamine (94.48 mg, 0.27 mmol) and 4-dimethylaminopyridine (66.76 mg, 0.54 mmol). The mixture was warmed to 75° C. and stirred for 2.5 hours. The mixture was treated with HCl 1 N and the slurry extracted several times with ethyl acetate. The combined organic phases were dried over magnesium sulphate and evaporated. The residue was purified by flash chromatography (dichloromethane/methanol gradient) to yield {4-[1-(5-chloro-2-methoxy-benzenesulfonyl)-1,2,3,4-tetrahydro-quinolin-7-ylcarbamoyl]-phenyl}-acetic acid methyl ester as an off-white solid, 134.20 mg (95%), MS (ISP): m/e=529.3 (M+H).
