1,1'-Thiocarbonyldiimidazole → HCID 59464031, compound

Participants

Reaction Steps

To a stirred solution of 4-(4-fluorophenoxy)aniline (190 mg, 0.93 mmol) in anhydrous DMA (4 mL) was added 1,1′-carbonothioylbis(1H-imidazole) (167 mg, 0.93 mmol) and the mixture stirred at ambient temperature for 1 hr. Methyl 1-(5-{[hydrazino(oxo)acetyl]amino}pyridin-2-yl)piperidine-4-carboxylate (250 mg, 0.78 mmol) was added and the reaction mixture was heated to 50° C. for 1 hr. EDCI.HCl (180 mg, 0.93 mmol) was added and the reaction mixture heated to 85° C. overnight and then allowed to cool to ambient temperature. Water (˜20 mL) was added and the suspension filtered, washed with ether (˜15 mL) and dried to leave the title compound as a pale yellow solid (415 mg, 0.780 mmol, 100%). 1H NMR δ 1.50-1.58 (m, 2H), 1.87-1.90 (m, 2H), 2.61-2.67 (m, 1H), 2.90-2.94 (m, 2H), 3.62 (s, 3H), 4.17 (d, 2H), 6.87-6.89 (m, 1H), 7.00-7.10 (m, 4H), 7.19-7.23 (m, 2H), 7.60-7.63 (m, 2H), 7.90-7.92 (m, 1H), 8.48 (s, 1H), 10.95 (s, 1H), 10.99 (s, 1H); MS m/e MH+ 533.
