Procedure

To a solution of the compound from Example 56 (102 mg) in CH2Cl2 (5 mL) at −10° C. was added TFA (1 mL). After warming to room temperature, the reaction mixture was stirred for a total of 1 hour while monitoring the progress by TLC. Upon consumption of the starting material, the reaction mixture was cooled to 0° C. and DIEA (4.5 mL) was added carefully. After 2 hours, water (20 mL) and EtOAc (30 mL) were added and the mixture shaken. The aqueous phase was then separated and extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by liquid chromatography (SiO2, EtOAc) and recrystallization from EtOAc/hexanes to give the titled compound (62 mg). MS (m/z) 402 (M); mp 187° C.
