Reaction Steps

3-Chloro-6,7,8,9-tetrahydro-5H-dipyrido[2,3-b;3′,4′-d]pyrrole (50 mg, 0.24 mmol), and DIEA (0.04 mL, 0.24 mmol) were dissolved in DCM (2 mL). 3-Methoxyphenyl isocyanate (0.03 mL, 0.24 mmol) was added dropwise, and the reaction solution was stirred overnight at room temperature. The crude reaction mixture was concentrated, and converted to the HCl salt by dissolving the crude material in MeOH (2 ml) and adding 1 M HCl/ether (2 equiv). The resulting solution was refrigerated overnight. Additional ether was added to drive precipitate formation. The resulting precipitate was filtered and dried under vacuum to provide 30 (28 mg, 30% yield) as a yellow solid. LC-MS (M+H=357, obsd.=357).
