Potassium Carbonate → (S)-ethyl 2-tert-butoxy-2-(5-(4-chlorophenyl)-2-(hydroxymethyl)-7-methylquinolin-6-yl)acetate

Participants

Reaction Steps

To a stirred solution of (S)-ethyl 2-(2-(acetoxymethyl)-5-(4-chlorophenyl)-7-methylquinolin-6-yl)-2-tert-butoxyacetate (0.095 mmol) in methanol (2 mL) was added 2 M K2CO3 (0.5 mL, excess) at room temperature. The mixture was stirred at room temperature for 1 hour, diluted with water. The mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried and concentrated in vacuo. The obtained residue was purified by flash chromatography to provide the desired product (26 mg, 62%). LCMS-ESI+ (m/z): 442.2, 444.2 (M+H)+.
