Procedure

To a solution of the compound prepared in Example 30 (0.010 mmol) in dichloroethane (0.7 mL) were added cyclopentanecarbonylchloride (0.020 mmol) and poly(4-vinylpyridine) (2% cross-linked, Aldrich, CAS#9017-40-7) (5.3 mg). The mixture was stirred overnight at 25° C. To the reaction mixture was added PS-trisamine (Argonaut, product number 800229, loading; 4.36 mmol/g) (6.9 mg), and the mixture was stirred overnight at 25° C. The mixture was filtered and the filtrate was concentrated to give the compound of the present invention having the following physical data.
