Reaction Steps

3-{[4-(4-Isopropyl-phenyl)-thiazol-2-yl]-thiophen-2-ylmethyl-amino}-propionic acid was prepared following general procedure I using 3-{[4-(4-isopropyl-phenyl)-thiazol-2-yl]-thiophen-2-ylmethyl-amino}-propionitrile (368 mg, 1 mmol), 1 N NaOH (aq) solution (4 mL) and ethanol (2 mL). The mixture was refluxed for 15 h. Trituration in hexanes gave 3-{[4-(4-isopropyl-phenyl)-thiazol-2-yl]-thiophen-2-ylmethyl-amino}-propionic acid. LCMS m/z: 387 (M+1)+. The sodium salt was prepared following general procedure J using 3-{[4-(4-isopropyl-phenyl)-thiazol-2-yl]-thiophen-2-ylmethyl-amino}-propionic acid (93.8 mg, 0.243 mmol), 1 N NaOH (aq) solution (0.243 mL), THF (1 mL) and MeOH (1 mL). Trituration in hexanes gave sodium 3-{[4-(4-isopropyl-phenyl)-thiazol-2-yl]-thiophen-2-ylmethyl-amino}-propionate.
