Into a 50 mL round bottom flask is placed 6.40 g (33.6 mmol) of p-toluenesulfonyl chloride and 25 mL of methylene chloride. The resulting solution is cooled with an ice bath as 4.00 g (31.0 mmol) of 1-piperidinoethanol in 6 mL of methylene chloride is added dropwise. After the addition is complete, the ice bath is removed and the resulting slurry is stirred for about 12 hours. The reaction mixture is concentrated on a rotary evaporator to yield a solid residue which may then be used as in Preparation 4 below.
