Sodium Bicarbonate → HCID 59398271, compound

Participants

Reaction Steps

To 25 mL of a chloroform solution containing 71 mg of (4-methyl-6-methoxy-2-oxoquinolin-1(2H)-yl)acetaldehyde and 108 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(piperidin-4-yl)carbamate, 18 μL of acetic acid was added, and stirred at room temperature for 1 hour. To the reaction mixture, 121 mg of sodium triacetoxyborohydride was added, and stirred for 2 hours. Aqueous saturated sodium hydrogen carbonate solution was added, the organic layer was separated. The organic layer was washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [Silica Gel; Kanto Chemical Co., Inc., Silica Gel 60, eluent; chloroform:methanol=20:1], to give 140 mg of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(4-methyl-6-methoxy-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate as a white solid.
