In a 50 ml sealed tube was added 2-biphenylylisocyanate (8 g, 41 mmol) in anhydrous acetonitrile (40 mL). To this solution was added N-benzyl-4-piperidinol (9.8 g, 51.25 mmol) and the tube was partially immersed in a silicon oil bath and heated to 85° C. After 16 h, the reaction mixture was cooled and concentrated in vacuo to give a 1-benzyl-4-piperidyl N-(2-biphenylyl)carbamate which was used in the next step without further purification.
