Procedure:
A solution of N,N-dimethyl-2-(6-nitro-3,4-dihydroquinolin-1(2H)-yl)ethanamine (500 mg, 2.01 mmol) in 10 mL CH2Cl2 was treated dropwise with phenylchloroformate (378 μL, 3.01 mmol).

Procedure:
To a refluxing mixture of potassium tert-butoxide (27 g, 242 mmol) and tert-butanol (150 mL) was added a solution of 4-fluoro-benzaldehyde (20 g, 161 mmol) and dimethyl succinate (28 g, 193.2 mmol) in tert-butanol (100 mL) dropwise.

Procedure:
Benzyl (1S,2R,4R)-4-(tert-butyldimethylsilyloxy)-2-(methoxy(methyl)carbamoyl)cyclohexylcarbamate (4.0 g) was dissolved in THF (40 mL) and cooled to −22° C. prior to the addition of 1.6 M MeLi (14.5 mL) in Et2O. After 40 min at −22° C., the reaction was quenched with 0.5 N HCl solution and extracted with EtOAc (2×). The organic extracts were combined, washed with brine, dried (MgSO4), filtered, and concentrated. The resulting residue was purified by flash chromatography to afford benzyl (1S,2R,4R)-2-acetyl-4-(tert-butyldimethylsilyloxy)cyclohexylcarbamate (5.7 g). MS found: (M+H)+=406.3.

Procedure:
53.4 g (0.3 mol) of 4-trifluoromethoxyphenol were allowed to drop at 25° C. in the course of 30 minutes into 75 ml of 30% strength nitric acid. The mixture was subsequently stirred for 2 hours at 25° C. and then poured into 500 ml of ice water, and the organic phase was separated off. Distillation of the latter yielded 56 g of product having a boiling point of 102° to 103° C. at 26 mbar, which corresponds to a yield of 83% of theory.

Procedure:
4.5 g of t-butyl 3-oxo-4-p-toluenesulphonyloxybutyrate were dissolved in 40 ml of acetic acid, and then 1.42 g of sodium nitrite were added, at room temperature, to the solution over a period of 10 minutes. The mixture was then stirred at room temperature for 50 minutes, after which 200 ml of ethyl acetate were added and the mixture was then washed with an aqueous solution of sodium chloride. The ethyl acetate solution was dried over magnesium sulphate and, after filtering off the drying agent, the filtrate was concentrated by evaporation under reduced pressure to give a brown, oily substance. This oily substance was purified by column chromatography through silica gel, eluted with a 4:1 by volume mixture of cyclohexane and ethyl acetate, affording 1.66 g of t-butyl 2-hydroxyimino-3-oxo-4-p-toluenesulphonyloxybutyrate, in the form of colourless crystals, melting at 106°-108° C. (with decomposition, recrystallized from a 1:1 by volume mixture of diethyl ether and petroleum ether).

Procedure:
A mixture of 5.2 parts of α-(2,4-dichlorophenyl)-1H-1,2,4-triazole-1-ethanol, 50 parts of dimethyl sulfoxide and 45 parts of benzene is stirred till all solid enters solution. Then there is added 1 part of a sodium hydride dispersion 78% and stirring is continued till gasevolution has ceased. After stirring for one hour at 40°-50° C., there are added 2.3 parts of 3-chloro-1-propyne. The whole is stirred overnight at room temperature. The reaction mixture is poured onto ice-water and the product is extracted with 1,1'-oxybisethane. The extract is washed with water, dried, filtered and evaporated. The oily residue is purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) as eluent. The pure fractions are collected and the eluent is evaporated. Upon standing overnight at room temperature, the residue solidifies. The product is filtered off and crystallized from 2,2'-oxybispropane, yielding 2 parts (33.8%) of 1-[2-(2,4-dichlorophenyl)-2-(2 -propynyloxy)ethyl]-1H-1,2,4-triazole; mp. 84° C.
