Benzyl Bromide → HCID 71268696, compound

Participants

Reaction Steps

55% sodium hydride (1.30 g) was added under ice-cooling to a THF (87 ml) solution of tert-butyl 4-(hydroxymethyl)-3,6-dihydropyridine-1(2H)-carboxylate (5.77 g), and this suspension was stirred at room temperature for 30 minutes. After ice-cooling again, benzyl bromide (5.32 g) and tetrabutylammonium iodide (1.00 g) were added thereto and stirring was performed at room temperature for 3 hours. After adding a saturated ammonium chloride aqueous solution, extraction was performed with EtOAc. A residue which was obtained by washing with saturated brine, drying over anhydrous magnesium sulfate, and concentration was purified by silica gel column chromatography (EtOAc/hexane) to obtain tert-butyl 4-[(benzyloxy)methyl]-3,6-dihydropyridine-1(2H)-carboxylate (6.16 g).
