Procedure

A mixture of 84 mg of 3(S)-isopropyl-5(S)-{1(S)-tert-butoxycarbonylamino-3(S)-isopropyl-4-[4-(3-hydroxypropyloxy)-3-(3-methoxypropyloxy)-phenyl]-butyl}-tetrahydrofuran-2-one, 0.6 ml of 4-(2-aminoethyl)-morpholine and 0.025 ml of glacial acetic acid is stirred for 16 hours at room temperature and for 6 hours at 45° C. and is then partitioned between diethyl ether (2×) and saturated NaHCO3 solution (1×) and water (2×). The organic phases are combined, dried over magnesium sulfate and concentrated by evaporation, and the residue is purified by means of FC (5 g of silica gel, dichloromethane/methanol=98:2), yielding the title compound: Rf (dichloromethane/methanol=95:5)=0.16; HPLC Rt =14.49 minutes; FAB-MS (M+H)+ =710.
