실험 절차

A solution of 387 mg (0.858 mmol) of tert-butyl(S)-6-tert-butoxycarbonylamino-2-(2-oxooxazolidine-3-sulfonylamino)hexanoate and 250 mg (0.780 mmol) of (9S,12R)-12-amino-9-isopropyl-2,7-dioxa-10-azabicyclo[12.2.2]octadeca-1(17),14(18),15-trien-11-one (compound 1-1E) in 15 ml of acetonitrile was stirred at 80° C. After 1 day (d), the same amount of the oxazolidine was again added, and the mixture was stirred for 1 d. The reaction mixture was then concentrated and the residue was purified by prep. HPLC. Product-containing fractions were combined, the acetonitrile was evaporated off, made slightly alkaline with sat. NaHCO3 solution and extracted several times with ethyl acetate. The combined organic phases were dried over Na2SO4, filtered and concentrated. 78 mg of the title compound were obtained.
