Participants

Reaction Steps

A mixture containing 4.3 g of 4-acetyl-1-ethoxycarbonyl-4-hydroxypiperidine, 6.0 g of tert-butyl isocyanate and 1 ml of triethylamine is refluxed under nitrogen for 6 hours. After cooling down and adding 50 ml of chloroform to the reaction mixture the organic phase is washed with water to neutral, then the solvent is evaporated under reduced pressure. The crude product obtained as evaporation residue is recrystallized from isopropyl ether to give the title substance in 44% yield, m.p.: 104°-105° C.
