Sodium Carbonate → HCID 15239360, compound

Participants

Reaction Steps

To 50 ml of a solution containing 9.00 g of 3-(4-t-butylphenyl)-4-hydroxycarbonyl-2-methyl-1-oxo-1,2,3,4-tetrahydroisoquinoline in dimethylsulfoxide, 4.20 g of sodium carbonate was added and the mixture was allowed to react at 150° C. for 1 hour. After the reaction, the solvent was evaporated under reduced pressure, and 800 ml of water was added thereto, followed by extraction with ethyl acetate (100 ml×5). The combined organic layers were washed with water (300 ml×6) and then with brine, and were dried over anhydrous magnesium sulfate. After evaporating the solvent under reduced pressure, the residue was purified by silica gel column chromatography [hexane/ethyl acetate (2/1)] to obtain 5.92 g of 3-(4-t-butylphenyl)-2-methyl-1-oxo-1,2,3,4-tetrahydroisoquinoline.
