Participants

Reaction Steps

The above alcohol (131 mg, 0.274 mmol), TFA (2.0 mL) and Et3SiH (0.23 mL) were combined according to general procedure O. After aqueous workup the residue was purified by silica gel chromatography (gradient, hexane→1/1 EtOAc-hexane). After concentration and trituration from hexane, 3-[(4-Benzhydryl-thiazol-2-yl)-cyclopentyl-amino]-propionic acid (45 mg, 40%) was obtained. LCMS m/z: 408 (M+1). The HCl salt was also prepared, using general procedure G2, by the addition of 4 M HCl in dioxane.
