By treatment of methyl 3β-acetoxy-7β-hydroxy-4,4,14-trimethyl-1-oxo-5α-chol-8-en-24-oate 3 with p-toluenesulfonyl chloride in pyridine methyl 3β-acetoxy-4,4,14-trimethyl-11-oxo 19-norchola-5,7,9-trien-24-oate 1a was synthesized and its structure confirmed by spectral evidence. From 3β-acetoxy-19-norlanosta-5,7,9-trien-11-one 1b the 7-amino derivative 1d, of which was prepared by nitration and selective catalytic hydrogenation (10% Pd/C) of the obtained 7-nitro compound 1c.
