Reaction Steps

To a cooded (5° C.) solution of 1-chloro-3-(4-aminothiophenoxy)propane (4.9 g, 0.024 mol) and pyridine (2.1 g 0.027 mol) in CH2Cl2 (50 mL) was added methanesulfonyl chloride (3.1 g, 0.027 mol). The mixture was stirred at room temperature for 16 hours, washed with 2 N HCl, brine, dried (MgSO4), and concentrated. Recrystallization from EtOH gave 4.0 g (59%) of product as a pink solid m.p. 61°-63° C.
