Chloroacetyl chloride → HCID 67537379, compound

Participants

Reaction Steps

1-methyl-1-(1,2,3,4-tetrahydroisoquinolin-1-yl)ethyl pivalate (2.79 g) was dissolved in a 1:4 mixed solvent (30 mL) of EtOAc-saturated aqueous sodium bicarbonate. A solution of chloroacetyl chloride (0.9 mL) in EtOAc (6 mL) was added dropwise to the reaction liquid under ice-cooling, followed by stirring at room temperature for 2 hours and extraction with EtOAc. The extract was washed with saturated brine, and then dried over magnesium sulfate. The solvent was evaporated and the resulting residue was purified by silica gel column chromatography (hexane-EtOAc) to obtain 1-[2 (chloroacetyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]-1-methylethyl pivalate (3.01 g).
