실험 절차

A mixture of 3.02 g (6.33 mmol) 5-methyl 1-(4-nitrophenyl) (6S)-6-(3,4-difluorophenyl)-4-(methoxymethyl)-2-oxo-3,6-dihydro-1,5(2H)-pyrimidinedicarboxylate, 1.50 g (5.80 mmol) of 3-(4-(3-nitrophenyl)-3,6-dihydro-1(2H)-pyridinyl)-1-propanamine, 7.94 g (75.5 mmol) of K2CO3 and 1.00 mL of methanol in 200 mL dichloromethane (under argon) was stirred at room temperature for 1 hour. The reaction mixture was filtered and concentrated in vacuo. The residue was dissolved in 100 mL of ethyl acetate and washed 3×50 mL of 5% aqueous NaOH solution, the organic layer was dried (MgSO4) and concentrated in vacuo. The residue was dissolved in 100 mL of anhydrous ethanol containing 0.50 g 10% Pd/C and the reaction mixture was stirred under a hydrogen balloon for 24 hours. The reaction mixture was passed through a column of Celite 545 filtering agent, washed with ethanol, the filtrate was dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography (silica, 9.5:0.5, dichloromethane:methanol+1% isopropyl amine) to afford 1.65 g (52.0% yield) of the desired product.
