Synthesis of (5-azido-2-nitrobenzoyl)amido, (4-azido-2-nitrophenyl)amino, and (5-azido-2-nitro-3,4,6-trifluorophenyl)amino derivatives of 17α-methylamino-, 17α-ethylamino-, and 17α-propylamino-5α-dihydrotestosterone as reagents of different linker lengths for the photoaffinity labeling of sex hormone binding globulins and androgen receptors

nitrile intermediates with cyano or cyanomethyl anions and subsequent reduction to amines with lithiumaluminumhydride, in the two other cases. The 3,3-dimethoxy group of these photoreagents was cleaved by acidolysis to a 3-ketone, which was reduced with sodium borohydride to a 3beta-alcohol. All of these compounds were characterized by (1)H- and (13)C-NMR as well as by (1)H, (13)C heteronuclear 2D NMR
