Reaction Steps

General procedure D was used to deprotect 0.4 grams (2.05 mmols) of 28 in 21 mL of dichloromethane and trifluoroacetic acid. After work-up, the TFA salt of 28 was then coupled to 0.6 grams (2.05 mmols) of 4-octylbenzoic acid with 1.1 grams (2.05 mmols) of PyBOP and 1.1 grams (8.2 mmols) of N,N-diisopropylethylamine in 21 mL of dichloromethane according to general procedure E and heating at 50° C. After previously described work-up and purification procedures (column chromatography, 25% EtOAc in hexanes) 0.256 grams (0.82 mmols, 40%) of the title product was recovered.
