Abstract
Novel 11 – H – pyrazolo – [31,41:17,16] – estra-4,9,11 – trien – 3 – one and 3 – hydroximino – 11 – H – pyrazolo – [31,41:17,16] – estra – 4,9,11-triene is obtained in a process which comprises reacting 3 – hydroximino – 16 – formyl – estra-4, 9,11 – trien – 17 – one with hydrazine to form 3 – hydroximino – 11 – H – pyrazolo – [31,41:17, 16] – estra – 4,9,11 – triene and reacting the latter with an agent effecting cleavage of the hydroximino group at the 3-position so as to form 11 – H – pyrazolo – [31,41:17,16] – estra-4 9,11-triene-3-one. The cleavage may for example be effected with formaldehyde, levulinic acid or pyruvic acid, or oxalic, sulphuric, hydrochloric, sulphurous, persulphuric or nitrous acids.
