Water → Tert-butyl 4-(hydroxymethyl)-4-(methoxymethyl)piperidine-1-carboxylate

Participants

Reaction Steps

To a solution of 1-tert-butyl 4-ethyl 4-(methoxymethyl)piperidine-1,4-dicarboxylate (2.05 g) in toluene (21 ml) was added 0.99 M solution of diisobutyl aluminum hydride in toluene (16.5 ml) under at 0° C. It was stirred at room temperature for 2 hours. Water was added and extracted with EtOAc. The organic phase was washed with water and brine, dried over MgSO4, evaporated off. The residue was purified by silica gel column to give tert-butyl 4-(hydroxymethyl)-4-(methoxymethyl)piperidine-1-carboxylate (0.95 g) as oil.
