Procedure:
A mixture consisting of 1.37 g (0.0100 mol) of benzohydroxamic acid, 10 ml of pyridine, and 100 ml of methylene chloride was prepared in a 250 ml round-bottom flask. The mixture was cooled in an ice bath and 2.00 g (0.101 mol) of diethylmalonyl chloride was added dropwise over a 15 minute period. The reaction mixture was stirred for one hour at room temperature after which time all the benzohydroxamic acid had dissolved. The solution was evaporated under reduced pressure, and to the residue was added 100 ml of cold water. The insoluble viscous oil was rubbed with a glass rod to effect solidification.

Procedure:
A suspension of potassium t-butoxide (1.44 kg) in dimethylformamide(6.61), cooled to −5° C. to −10° C., was treated with a mixture of 2-nitroanisole (690 g) and methyl dichloroacetate (915 g) over 4 hours, whilst maintaining the temperature below −5° C. The reaction mixture was then treated with acetic acid (770 ml), then with water (6.6 l) and then extracted three times with tert-butyl methyl ether (5.5 l). The combined extracts were washed with water (5.5 l), then with saturated sodium bicarbonate solution (5.5 l), then with saturated brine (5.5 l) and then dried over magnesium sulphate to give a solution of methyl α-chloro-3-methoxy-4-nitrophenylacetate. This solution was concentrated to half volume under reduced pressure and then treated with tetrahydrofuran (2l), followed by triethylamine (751 ml), followed by 10 % palladium on chareoal (58.4 g) and the mixture was hydrogenated under a pressure of 50 psi hydrogen at 50° C. for 8 hours. The mixture was cooled to room temperature and filtered. The filtrate was dried over magnesium sulphate to give a solution of methyl 4-amino-3-methoxyphenylacetate which was heated to reflux and then treated with o-tolyl isocyanate (598.5 g) over 30 minutes. After heating at reflux temperature for a further 3 hours, during which time a solid was deposited, the mixture was cooled to room temperature. The solid was collected, washed twice with tert-butyl methyl ether (4 l), then dried in a vacuum oven at 60° C. to give the title compound (764.8 g) as a white solid, m.p. 167-168° C.

Yield: 61.1 %

Procedure:
1.13 g (3 mmol) of (S)-8-chloro-1-(5-chloromethyl-1,2,4-oxadiazol-3-yl)-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one were stirred at 70° for 4 hours with 2 g (17 mmol) of 2,6-dimethylpiperidine and 15 ml of N,N-dimethylformamide. By evaporation of the reaction mixture and chromatography of the residue on silica gel while eluting with ethyl acetate/methanol 9/1 there was obtained 0.83 g (61%) of (S)-8-chloro-1-[5-(2,6-dimethylpiperidin-1-yl)methyl-1,2,4-oxadiazol-3-yl]-12,12a-dihydro-9H,11H-azeto[2,1-c]imidazo[1,5-a][1,4]benzodiazepin-9-one, which was converted into the hydrochloride of m.p. 233°-236°.

Procedure:
50 mg (0.17 mmol) of the compound of Example 6A and 37 mg (0.17 mmol) of the compound of Example 43A were reacted analogously to the procedure of Example 15, except that here only 6 ml of 0.1 M aqueous sodium hydroxide solution (instead of 15 ml) were used for work-up. The product obtained was re-purified by preparative HPLC (column: Reprosil-Pur C18, 10 μm, 250 mm×30 mm; mobile phase: methanol/water with 0.05% TFA, with gradient). The product-containing fractions were combined and concentrated under reduced pressure, and the residue was dissolved in ethyl acetate and washed successively with saturated potassium carbonate solution and saturated sodium chloride solution. The organic phase was dried over sodium sulphate, filtered and concentrated under reduced pressure. Drying of the residue gave 44 mg (97% pure, 51% of theory) of the title compound.

Procedure:
4-Benzoyl-17β-hydroxy-5α-androstan-3-one made as in Example 1 (788 mg, 2 mmole) in 2 ml of CH2Cl2 is added to pyridinium chlorochromate (650 mg, 3 mmole) suspended in CH2Cl2 (2 ml) at 25° C. After 2 hours, ether is added and the solvent decanted. This is then filtered through Florisil, the eluate evaporated and the residue recrystallized from chloroform-heptane.
