Sodium borohydride (0.12 mmol) was added to a solution of cis 2-(1-hydroxy-2,2,2-trichloroethyl)-3,3-dimethylcyclopropane carboxylic acid (0.12 mol) in dry dimethylformamide (0.4 ml), and the mixture was heated for 30 minutes at 80° C. An additional amount of 0.12 mmol sodium borohydride was then added and the mixture was heated for a further 15 minutes at 80° C. It was then diluted with water, acidified with concentrated HCl and extracted with deuterochloroform, CDCl3. The extract was washed with water and analysed by NMR, which showed a yield of 25% of the desired product, with 30% of unconverted starting material.
