1,1'-Carbonyldiimidazole → HCID 86645283, compound

Participants

Reaction Steps

To a solution of 2-amino-N-benzyl-4-methylthiazole-5-carboxamide (0.37 g, 1.50 mmol) in tetrahydrofuran (20 mL) was added 1,1′-carbonyldiimidazole (0.31 g, 1.91 mmol) at ambient temperature. The resulting reaction mixture was stirred at ambient temperature for 11 hours, followed by the addition of N-(2,2-dimethoxyethyl)-4-fluoroaniline (0.40 g, 2.00 mmol). The reaction mixture was kept stirring for 17 hour at ambient temperature. The solvent was removed in vacuo, and the residue was purified by column chromatography to afford the title compound in 68% yield (0.48 g): 1H NMR (300 MHz, CDCl3) δ 7.36-7.12 (m, 10H), 5.89 (t, J=5.7 Hz, 1H), 4.61 (t, J=5.4 Hz, 1H), 4.53 (d, J=5.4 Hz, 2H), 3.76 (t, J=5.7 Hz, 2H), 3.31 (s, 6H), 2.51 (s, 3H); MS (ES+) m/z 473.4 (M+1).
