Reaction Steps

Next, 0.82 g of Li[AlH4 ] was added to 50 ml of dried (C2H5)2O, and the resulting mixture was stirred. Thereto was gradually added 5 g of 4-[p-(2-hydroxycarbonylethyl)phenyl]pentylcyclohexane. Thereafter the thus obtained mixture was stirred for 5 hours, and filtered. The (C2H5)2O was distilled off from the filtrate, and the residue was recrystallized from n--C6H14 to obtain 4-[p-(3-hydroxypropyl)phenyl]pentylcyclohexane. The melting point of this compound was 70.7° to 72.5° C. To a mixture of 3.6 g of SOCl2, one drop of pyridine and 50 ml of benzene was added 4.3 g of the 4-[p-(3-hydroxypropyl)phenyl]pentylcyclohexane obtained above, and the resulting mixture was refluxed for 5 hours. Thereafter, the surplus SOCl2 was distilled off to obtain 4-[p-(3-chloropropyl)phenyl]pentylcyclohexane. The melting point of this compound was 70.7° to 72.5° C.
