Reaction Steps
2.81 g of the (R,S)-4-[4'-(3"-hydroxy-1"-methylbutoxy)phenyl]benzonitrile prepared in the above Example 1 was mixed with 5.10 g of acetic anhydride and 0.3 g of pyridine. The mixture was stirred at 100° C. for one hour. After cooling, the reaction mixture was carefully poured into 50 ml of 2N hydrochloric acid and extracted with diethyl ether. After washing with water, drying and desolvating, the obtained residue was purified by silica gel column chromatography with the use of a mixture of n-hexane and ethyl acetate (3:1) as a developing solvent. Thus 2.65 g of (R,S)-4-[4'-(3"-acetoxy-1"methylbutoxy)phenyl]benzonitrile was obtained.
