Procedure:
Sodium metaperiodate (1.85 g, 8.68 m.mol.) was added to a stirred, cooled (5°) solution of N-cyano-N'-methyl-N"-[2-((4-methyl-5-imidazolyl) methylthio)ethyl]guanidine (2.085 g, 8.27 m.mol.) in water (83 ml). After 90 minutes stirring at 5° thin layer chromatography indicated almost complete disappearance of starting material. The solution was allowed to stand overnight at room temperature to complete the reaction, then evaporated under reduced pressure to dryness, with azeotroping with n-propanol. The residue was boiled with isopropanol (60 ml), filtered hot, and the filtrate was evaporated to dryness to give the crude product as a glass. This was purified by charcoaling in methanol (40 ml), filtration and dilution with ether to 1500 ml. The liquid was decanted from the flocculent precipitated glass which was kept under a further 1500 ml ether to become semicrystalline, then filtered and allowed to stand overnight in air. The hardened glass was stirred with cold methanol (25 ml) filtered from insoluble crude product and and inorganics (0.28 g. m.p. 190°) and to the filtrate was carefully added ether (to 500 ml) so that two layers formed. On standing undisturbed for three days there separated off white crystals of N-cyano-N'-methyl-N"-[2-((4-methyl-5-imidazolyl)methylsulphinyl)ethyl] guanidine (1.55 g), m.p. 185°-186.5°C.

The layers were separated and the aqueous layer was extracted with 3 15-ml portions of dichloromethane. The combined organic extracts were dried (Na2SO4) and evaporated. Chromatography (SiO2, CH2Cl2/methanol 19:1 yielded 236 mg (52%) 2-Chloro-N-methyl-4-(4-methyl-piperazin-1-yl)-benzamide as a light yellow solid, MS (EI): 2.67(M+).

Procedure:
Acetone cyanohydrin (82 ml), potassium cyanide (1 gm) amd water (2 ml) are added to a slurry of androst-4-en-3,17-dione (0.80 g) in methanol (400 ml) and water (40 ml) at 35°. The reaction becomes homogeneous and on continued stirring a heavy slurry develops. After 3 hours, 120 ml of water is added dropwise, and the slurry allowed to stir overnight at 20°-25°. The slurry is then cooled in an ice bath, filtered, and the solids washed with methanol/water (1/1). The solvents are dried under reduced pressure to give 70.4 g of the title compound. An additional 13.17 g of product is isolated from the mother liquor on partial evaporation, m.p.=159°-160.5°; [α]D (c=1, CHCl3)=+145.9°; MS=313, 298, 286, 245 and 124 m/e; NMR (CDCl3)=1.00, 1.20, 3.5 and 5.72 δ.
