    • note
    • Stability studies of the polymer-bound activated ester 10a showed that, in suspension in neat DMF and in the presence of N-ethyldiisopropylamine, 62% of 10a is decomposed during 25 h to give the starting polymer 4 and the free carboxylic acid in solution. Stored under appropriate conditions, the activated esters of 4 were quite stable. After storage in dry form for two months at +4°C and under nitrogen, 10a still gave quantitative yield when reacted with phenethylamine.
