2-Methoxyethylamine → 3-[6-(4-hydroxy-3-methylphenyl)-2-oxo-2,3-dihydropyrimidin-4-yl]-N-[2-(methyloxy)ethyl]benzamide

Participants

Reaction Steps

To a solution of 3-(6-(4-hydroxy-3-methylphenyl)-2-oxo-2,3-dihydropyrimidin-4-yl)benzoic acid (16.9 mg, 48 umol) and 2-methoxyethanamine (3.0 mg, 40 umol) in dichloroethane (1.25 mL) and N,N-dimethylformamide (0.79 mL) was added 1-hydroxybenzotriazole (6.8 mg, 50 umol) followed by 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide methiodide (17.8 mg, 60 umol). The resultant mixture was stirred at room temperature for 15 hours. The reaction mixture was concentrated in vacuo. Purification of the residue by HPLC (reverse-phase, acetonitrile/water with 0.1% formic acid) followed by concentration in vacuo gave the title compound 3-[6-(4-hydroxy-3-methylphenyl)-2-oxo-2,3-dihydropyrimidin-4-yl]-N-[2-(methyloxy)ethyl]benzamide (5.4 mg, 36%).
