Boron trifluoride etherate → HCID 23039693, compound

Participants

Reaction Steps

A mixture of 11.6 g (92 mmoles) of 2-fluorobenzyl alcohol and 21.9 g (92 mmoles) of 2-(2,4-dichlorophenyl)-1,2-epoxypentane is added dropwise at 0°-2° C. to a solution of 2.0 ml (16.5 mmoles) of boron trifluoride ethyl etherate in 10 ml of diethyl ether. The solution is allowed to react further overnight at +7° C. and is worked up as in Example I by extraction and column chromatography. 2.95 g of the pure product are obtained in the form of a colourless oil. 100 MHz-1H-NMR (CDCl3): δ=6.8-7.7 ppm (m, 7H aromatic); 4.5 ppm (s, 2H, ##STR27## 3.9-4.4 ppm (m, 2H, --CH2OH); 1.7-2.3 ppm (m, 3H, --CH2CH2CH3 and OH); 0.7-1.4 ppm (m, 5H, --CH2CH3).
