실험 절차

Dimethyl 5-aminoisophthalate was mesylated by treating with methane sulfonylchloride and pyridine in dichloromethane. Then N-alkylation with methyl iodide under NaH/DMF condition gave dimethyl 5-(N-methylmethylsulfonamnido)isophthalate. Selective hydrolysis of dimethyl 5-(N-methylmethylsulfonamido)isophthalate, followed by EDC/HOBT/DIPEA mediated coupling with cc-methylbezylamine provided methyl 3-(N-methylmethylsulfonamido)-5-(1-phenylethylcarbamoyl)benzoate. Ester hydrolysis using aq. 1N NaOH in presence of THF/MeOH provided pure 3-(N-methylmethylsulfonamido)-5-(1-phenylethylcarbamoyl)benzoic acid as white solid.
