Participants

Reaction Steps

Benzyl-4-oxo-2-phenylpiperidine-1-carboxylate (1.64 g, 5.30 mmol) in THF (27 ml) was cooled to −78° C. and phenylmagnesium bromide (6.36 ml, 6.36 mmol) was added. The ice bath was removed and the solution stirred at room temperature for 2 h. Concentrate, dilute with EtOAc and wash twice with water. The organics were dried over MgSO4, concentrated, and purified on silica gel eluted using 30% EtOAc to afford 1.02 g of benzyl 4-hydroxy-2,4-diphenylpiperidine-1-carboxylate.
