Reaction Steps
In a dry ice-acetone bath under an argon atmosphere, a solution of 1.0 M methyllithium in diethyl ether (16.2 mL) was added dropwise to a solution of ethyl 2-benzyl-1,2,3,4-tetrahydroisoquinoline-1-carboxylate (1.99 g) in THF (20 mL) over 15 minutes. The reaction liquid was stirred in a dry ice-acetone bath for 0.5 hours and then further stirred in an ice bath for 1 hour. The reaction liquid was cooled again in the dry ice-acetone bath, and a solution of 1.04 M methyllithium in diethyl ether (3.24 mL) was added thereto. The reaction liquid was stirred in the dry ice-acetone bath for 0.5 hours and then stirred in the ice bath for 1 hour. Water was added to the reaction liquid, followed by extraction with EtOAc. The extract was washed with saturated brine, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane-EtOAc) to obtain 2-(2-benzyl-1,2,3,4-tetrahydroisoquinolin-1-yl)propan-2-ol (1.27 g).
