실험 절차

Pyridine (3.22 ml) was added to an ice-cold solution of 2-(1-(tert-butoxycarbonyl)-4-piperidyl)-ethanol (7.6 g) in dichloromethane (33 ml) followed by chloromethyl chloroformate (3.23 ml) at such a rate that the temperature was kept below 10° C. After stirring overnight at room temperature the reaction mixture was washed twice with 0.5 M HCl followed by water and aqueous sodium bicarbonate. The organic phase was dried over magnesium sulfate, filtered and evaporated in vacuo to yield the title compound as a colourless oil.
