反応手順

Water (50 ml) was added to a solution of (2α,3α,5α,16β,17β)2,3-epoxy-16-(1-pyrrolidinyl)-androstan-17-ol (85.2 g) in morpholine (500 ml) and the reaction mixture was heated at reflux temperature for 3 d. Evaporation of the reaction mixture gave a crude product, which was crystallised from acetone. Recrystallisation from methanol gave pure (2β,3α,5α,16β,17β)-2(4-morpholinyl)-16-(1-pyrrolidinyl)-androstane-3,17-diol (71.2 g), m.p. 212°-219° C.; [α]D20 =+87.9° (c 1.02 in CHCl3).
