Phenyl isocyanate → 2-Amino-3-(4-chlorobenzoyl)-6-(((phenyl)amino)carbonyl)-4,5,6,7-tetrahydrothieno (2,3-c)pyridine

Participants

Reaction Steps

To a stirred solution of 2-amino-3-(4-chlorobenzoyl)-4,5,6,7-tetrahydrothieno(2,3-c)pyridine) (1.02 mmol) in dry CH2Cl2 (20 mL), Et3N (1.2 eq) and phenylisocyanate (1.2 eq) were added. The mixture was stirred at room temperature for 4 hours, then was concentrated at reduced pressure and the residue purified by flash chromatography (EtOAc/light petroleum 3/7) to afford the desired compound as a solid (mp 216-217 ° C.).
