Participants

Reaction Steps

2-({Cyclopentyl-[4-(4-isopropyl-phenyl)-thiazol-2-yl]-amino}-methyl)-benzoic acid (19 mg) was prepared following general method S2 using cyclopentyl-[4-(4-isopropyl-phenyl)-thiazol-2-yl]-amine (80 mg, 0.28 mmol), 2-bromomethyl-benzoic acid methyl ester (68 mg, 0.33 mmol) and NaH (34 mg, 60%, 0.84 mmol). Purification (Silica gel, ethyl acetate/hexane 5:95) provided the ester, which was hydrolyzed following general procedure T. Sodium 2-({cyclopentyl-[4-(4-isopropyl-phenyl)-thiazol-2-yl]-amino}-methyl)-benzoate was prepared following procedure J. LCMS m/z: 422 (M+1)+.
