Portionwise at ambient temperature add NaH (1.88 g, 47.1 mmol, 60% in mineral oil) over 5 minutes. Heat reaction to reflux (90 C. bath temperature) overnight. Evaporate to thick red-brown oil and partition between Et2O (100 mL) and H2O (60 mL). Separate layers and extract H2O with Et2O (2*75 mL). Acidify the aqueous layer with 1.0 N HCl to pH 1 (becomes cloudy white suspension) and extract aqueous layer with CH2Cl2 (3*100 mL). Dry pooled CH2Cl2 layers over Na2SO4, filter and concentrate to yellow oil (7.5 g, 26.5 mmol). Use without further purification. LCMS=281.9 (MH+); 279.8 (M-)

Preparation of alpha-(2,4-dichlorophenyl)-alpha-hydroxymethylene acetonitrile 0.6 g of metal sodium was added to dry ethanol to obtain an ethanol solution of sodium ethoxide. Then, a mixed liquid comprising 37.2 g of 2,4-dichlorophenyl acetonitrile and 22.2 g of ethyl formate, was added thereto under heating to 70 C. After the addition, the mixture was further heated and refluxed for 2 hours and then, left to stand for 1 day. The reaction solution was cooled to 0 C. and then subjected to filtration. After washing with diethyl ether, the sodium salt collected by filtration was added to 130 ml of distilled water, and 9 ml of acetic acid was dropwise added thereto under cooling at 0 C. After the dropwise addition, the mixture was stirred at room temperature for about 30 minutes. Then, the formed precipitate was collected by filtration and washed with water. It was dried to obtain 31.7 g (yield: 74%) of the desired product. Melting point: 162-163 C.

Safety of 2-(2,4-Dichlorophenyl)acetonitrile

A suspension of sodium hydride (2.16 g) in dry dimethylsulphoxide (DMSO: 70 ml) was stirred at 50 C. under a nitrogen atmosphere for 2.5 hours and then cooled to 15 C. in an ice bath. A mixture of 2,4-dichlorophenylacetonitrile (8.37 g) and 3-methanesulphonyloxyhex-1-yl methanesulphonate (14.27 g) in DMSO (70 ml) was added dropwise to this solution over 15 minutes. The reaction mixture was stirred at room temperature for 0.5 hours, at 90 C. for 3 hours, and at 130 C. for 2 hours, and was then allowed to cool, diluted with water, and extracted with ether. The extracts were washed with water, dried over magnesium sulphate and concentrated to give a dark coloured oil (7.76 g). Purification of this crude product by bulb-to-bulb distillation gave a mixture of diastereomers of 1-cyano-1-(2,4-dichlorophenyl)-3-prop-1-ylcyclopentane (4.95 g, 39%) as a colourless oil (oven temperature: 230 C., ca. 10 torr).
