Procedure

A solution of N,N-dimethylaniline (24.0 mL) in toluene (20.0 mL) was bubbled with hydrochloride gas to prepare the corresponding hydrochloride. To the mixture were added 2-(3-hydroxypropyl)-6-methylphenol (20.0 g) and methanesulfonyl chloride (10.2 mL), and the resulting mixture was stirred at 110° C. for 1.5 hours. After cooling, methanol (2.4 mL) was added to the reaction mixture. The mixture was washed with distilled water, an aqueous sodium bicarbonate solution, distilled water and brine successively and then evaporated to give a solution of 2-(3-chloropropyl)-6-methylphenol (19.9 g) in toluene (21 g). NMR spectrum of this compound was identical with that of Reference Example 12.
