Reaction Steps

2.20 g (6.68 mmol) of 2-fluoro-3-formyl-6-(4-octyloxyphenyl)pyridine, 1.26 g (6.68 mmol) of 2-octylpropane-1,3-diol, 0.02g (0.10mmol) of p-toluenesulfonic acid and 3.00 g of sodium sulfate are stirred in 100 ml of toluene at room temperature for 68 hours. 0.14 ml (1.00 mmol) of triethylamine is then added, sodium sulfate is filtered off, the filtrate is concentrated, and the residue is purified by chromatography (silica gel, 9:1 hexane/ethyl acetate) and by recrystallization from acetonitrile, giving 1.40 g of 2-fluoro-3-(5-octyl-1,3-dioxane-2-yl)-6-(4-octyloxyphenyl)pyridine. ##STR63##
