Reaction Steps

40.6 g (0.17 mol) of 3,5-dichloro-4-hydroxybiphenyl (prepared according to J. C. Colbert et al., JACS 56, 202 (1934)) and 17.2 g (0.17 mol) of triethylamine are dissolved in 170 ml of ethyl acetate and admixed dropwise with 18.4 g (0.17 mol) of ethyl chloroformate at 10° C. The reaction solution is stirred overnight and washed with water, and the organic phase is concentrated. For further purification, the crude product (51.2 g) is chromatographed over silica gel using the system chloroform. 48 g (yield 90.8% of theory) of (2,6-dichloro-4-phenyl-phenyl) ethyl carbonate are obtained as an oil, log p (pH 7.5): 4.65.
