B-nor-17-oxoandrost-5-en-3b-yl acetate (1) was used as the starting material, which was transformed to the key intermediate of the synthesis, B-nor-17b-dimethyl-tert-butylsilyloxyandrost-4-en-3b-yl acetate (7). %K 5-azasteroids %K B-nor-17-oxoandrost-5-en-3b-yl acetate %K 3b-hydroxy-17b-dimethyl-tert-butylsilyloxy-5-azaandrostane %U http://www.shd.org.yu/HtDocs/SHD/Vol69/No11/V69-No11-04.pdf
