실험 절차

To a stirred solution of {1-[6-(3-cyano-5-methyl-benzoyl)-5-isopropyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-ylmethyl]-cyclopropyl}-acetic acid (90 mg, 0.22 mmol) in THF (5 mL) cooled in an ice bath, were added oxalyl chloride (38 μL, 0.44 mmol) and one drop of DMF. After stirring for 1 hr., the mixture was evaporated in vacuo. The residue was dissolved in THF (8 mL) and p-methoxy benzylamine (261 μL, 2 mmol) was added. After stirring for 1 hr., the mixture was evaporated in vacuo and the residue was purified by silica gel column chromatography (eluent, ethyl acetate:hexane (2:1): Rf=0.25 fraction was collected) to give 97 mg (83%) of 2-{1-[6-(3-cyano-5-methyl-benzoyl)-5-isopropyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-ylmethyl]-cyclopropyl}-N-(4-methoxy-benzyl)-acetamide (84) as a white solid. 1H-NMR (200 MHz, CDCl3) δ 0.40-0.46 (4H, m), 1.12 (3H, d, J=6.6 Hz), 1.23 (3H, d, J=6.6 Hz), 2.00 (1H, d, J=15.4 Hz), 2.25 (1H, m), 2.48-2.55 (4H, m), 3.45 (1H., d, J=15.4 Hz), 3.80 (3H, s), 3.90 (1H, d, J=15.4 Hz), 4.34-4.39 (2H, m), 6.69 (1H, m), 6.83-6.90 (2H, m), 7.22-7.30 (2H, m), 7.81 (1H, s), 8.01 (1H, s), 8.07 (1H, s), 9.81 (1H, s).
