Reaction Steps

The compound [3-(2-{(1S,2S)-1-[(2,4-dimethyl-benzylamino)-methyl]-2-hydroxy-pentylcarbamoyl}-acetylamino)-5-trifluoromethyl-phenyl]-carbamic acid tert-butyl ester (45 mg, 0.08 mmol, see procedure 8b above) was dissolved in CH2Cl2 (1.5 mL) and treated with TFA (0.5 mL). The solution was stirred for 3 h and then concentrated in vacuo. The residue was dissolved in benzene and concentrated in vacuo; this procedure was repeated. The residue was purified by reverse-phase HPLC to afford the title compound as a white powder after lyopholization. MS found: (M+H)+=495.4.
