Procedure

[1-{4-[{2-[3-Methoxy-4-[3-o-tolyl-ureido]-phenyl]-acetyl}-methyl-amino]-phenyl}-cyclopentyl]-acetic acid tert-butyl ester [0.18 g, Reference Example 8(b)] was treated with a mixture of trifluoroacetic acid (6 mL), dichloromethane (1.2 mL) and water (0.75 mL)and the resulting solution was then stirred at room temperature, under argon, for 1.5 hours. The amber coloured reaction mixture was evaporated and the residue was chased twice with toluene (20 mL) to yield an amber gum. This gum was triturated with pentane and the solid obtained was washed with pentane and then dried at 60° C., under vacuum, to give the title compound (0.13 g) as a pale yellow solid, m.p. softens at 100° C. then slowly melts from 118–150° C.
