To a solution of N-[2-(3-hydroxypropoxy)phenyl]-acetamide (Example 113) (7.5 g, 36 mmol) in pyridine (90 ml), cooled to 0° C., was added p-toluenesulfonyl chloride (13.6 g, 56 mmol). After the tosyl chloride went into solution, the reaction was then allowed to stand at 5° C. for 16 hours. The reaction was poured onto ice, and a brown oil settled. The aqueous supernatant was decanted from the oil, and the residual oil taken up in diethyl ether. The diethyl ether was washed with cold (5° C.) 3N HCl and then with brine. The organic layer was dried (MgSO4), and concentrated to afford a thick, brown oil, 5.3 g.
