Procedure

8.68 g (20 mmol) of pentyltriphenyl-phosphonium bromide+sodium amide (1 g contains 2.3 mmol of pentyltriphenyl-phosphonium bromide), 0.2 g (0.67 mmol) of 3,16α-dihydroxy-estra-1,3,5(10)-triene-9-carbaldehyde and 30 ml DMSO are introduced into a reaction flask that was rendered inert. The reaction mixture is treated for about 2 hours in an ultrasound bath at 60° C. After the reaction is completed, water is added to the reaction solution. The crude product is isolated by extraction with ethyl acetate, washing of the organic phase with water and concentration by evaporation until a dry state is reached.
