PROCEDURE

实验过程

A solution of 2,2-diethoxy-1-diazoethane (prepared from 0.0935 mole of N-2,2-diethoxyethyl urea by the method of W. Kirmse and M. Buschhoff, Chem. Ber., 100, 1491 (1967)) in 300 ml of 3:2 ether-pentane is diluted with 100 ml of methanol and cooled to 0°C. 21-Chloro-11β,16α,17-trihydroxypregna-1,4-diene-3,20-dione, 16,17-cycloborate is added in portions until nitrogen evolution ceases. The solvent is removed in vacuo to yield the title compound.
