実験手順

Tert-butyl 4-(4-fluorophenyl)-5,6-dihydropyridine-1(2H)-carboxylate (48 mg, 0.173 mmol) was dissolved in EtOH (2 ml), followed by addition of Pd (10 wt % on activated carbon, 5 mg), and then the resulting liquid was stirred at room temperature under hydrogen stream for 2 hours. The resulting reaction liquid was filtered, concentrated under reduced pressure, and dried under vacuum, to obtain 46 mg of colorless oil (95%).
