실험 절차

2-Fluoro-4-nitrotoluene (commercially available) was converted with the use of N-bromosuccimimide into the intermediate 2-fluoro-4-nitrobenzyl bromide, and subsequently into diethyl 2-fluoro-4-nitrobenzylphosphonate, in accordance with the specification of D. H. Wadsworth et al. in the Journal of Organic Chemistry, Vol. 30 (1965) p. 680-685. The title compound was prepared by the same procedure as described in Example 2. Making use of 23.6 g of 4-((2,2-dimethyl-1,3-dioxa-4-cyclopentyl)methyloxy)benzaldehyde and 29.1 g of diethyl 2-fluoro-4-nitrobenzyl phosphonate there were obtained in all 21 g of 4-(2,3-dihydroxypropyloxy)-2'-fluoro-4'nitrostilbene with a melting point of 110° C. and a clearing temperature of 129° C.
