PROCEDURE

实验过程

Into 1 ml of stirred solution of 1 mg of α-MSH in a 8:2 mixture of acetonitrile and water placed in a polyethylene test tube under Ar and containing 0.07 mg of triethylamine (TEA), 2.15 mg of NHS-Chlidea (prepared in Example 14a) in a small volume (about 0.2 ml) of acetonitrile was added and shortly sonicated. The reaction mixture, sealed under Ar, was stirred at room temperature in the dark for 66 hrs. In the course of the reaction, aliquots of 15 μl were taken from the reaction mixture, after 0, 3, 19, 45 and 66 hrs from the beginning of the reaction, and were subjected to HPLC analysis.
