実験手順

A solution of 4.7 g (32.8 mmol) of dimethylsulfamyl chloride in 5 ml of dry pyridine is added to 5.0 g (16.4 mmol) of 3-amino-4-benzyloxyphenyl 2-pyridyl ketone in 100 ml of dry pyridine at 0°-10° C. The reaction mixture is stirred in the cold overnight and then poured in water and extracted with ether. The ether extract is washed with water and extracted with dilute aqueous KOH. This basic extract is washed with ether, acidified with hydrochloric acid and extracted with methylene chloride. The dried organic extract is evaporated in vacuo to give 4-benzyloxy-3-dimethylsulfamoylaminophenyl 2-pyridyl ketone. Hydrogenation over PcO2 according to the procedure of Example 3 gives α-(4-hydroxy-3-dimethylsulfamoylaminophenyl)-2-piperidylcarbinol.
