Reaction Steps

Preparation of 3,5-difluoro-4-cyanophenyl 4-(trans-4-(ethoxymethyl)cyclohexyl)benzoate (in the formula (1), R=C2H5, l=1, m and n=both, 1, o=0, A1 =trans-1,4-cyclohexylene group, A2 =1,4-phenylene group, Z1 =covalent bond, Z2 =--COO--, X=CN, and Y1 and Y2 =both, F) (Compound No. 187) 4-(Trans-4-(ethoxymethyl)cyclohexyl)benzoic acid (1.9 g, 7.1 mmol) was mixed with thionyl chloride (1.3 g, 10.6 mmol), pyridine (0.1 ml) and toluene (4 ml), followed by reacting them at 80° C. for 2 hours, and distilling off superfluous thionyl chloride and toluene under reduced pressure, to obtain raw 4-(trans-4-(ethoxymethyl)cyclohexyl)benzoyl chloride.
