Procedure
Thionyl chloride (0.15 mL) was added to a solution of ethyl 4-(3-(2-propyl-4-cyclohexylphenoxy)propoxy) mandelate of Step C (0.71 g), pyridine (0.19 mL), and toluene (15 mL). The reaction mixture was stirred 6-7 h and then partitioned between ethyl acetate and water. The organic layer was washed twice with water, once with brine, dried over sodium sulfate, and filtered. The solvent was removed in vacuo and the resulting oil was used as such for the next step.
