Reaktionsschritte

Triethylamine (1.57 ml, 11.3 mmol) was added to a solution of 3-hydroxy-2,2-dimethyl-3-(4-pyridyl)propionitrile (1.00 g, 5.67 mmol) in dichloromethane (20 ml) at room temperature. Further, p-toluenesulfonyl chloride (1.30 g, 6.80 mmol) was added to the mixture, and the whole was warmed at 50° C. with stirring for three days. The reaction mixture was allowed to stand and then concentrated under reduced pressure, and the concentrate was purified by silica gel column chromatography to give 699 mg (37.4%) of 2,2-dimethyl-3-(4-pyridyl)-3-(p-tolylsulfonyloxy)propionitrile as a pale yellow solid.
