実験手順

Compound 29c was prepared as described hereinabove for Compound 29a, using Compound 25 (0.596 gram, 1.6 mmol), 2-[2-(2-{2-[2-(2-(tert-Butyl-dimethyl-silanyloxy)-ethoxy]-ethoxy}-ethoxy)-ethoxy}-ethoxy]-ethanol (Compound 28c, 0.957 gram, 2.4 mmol), and potassium trimethylsilonate (0.621 gram, 4.74 mmol) dissolved in DMSO (37 ml). The crude residue was purified by silica gel column chromatography, using a mixture of 2% methanol in dichloromethane as eluent, to obtain Compound 29c (0.568 gram, 56%).
