Reaction Steps
Isopropylsulphonyl chloride (5.6 ml, 50 mmol) was added dropwise to an ice-cooled solution of 4-piperidone ethylene ketal (6.4 ml, 50 mmol) and triethylamine (7.7 ml, 55 mmol) in dichloromethane (100 ml), and the reaction stirred at room temperature for 3 hours. The mixture was washed with water (2×), dried (MgSO4), filtered and evaporated in vacuo. The residue was crystallised from ether/pentane to afford the title compound as a solid, (10.55 g, 85%).
