1,3-Propanediamine, N'-(ethylcarbonimidoyl)-N,N-dimethyl-, monohydrochloride → Tert-butyl 5-(6-(1-phenylcyclopropyl)-2-thioxo-1,2-dihydropyridin-3-ylcarbamoyl)isoindoline-2-carboxylate

Participants

Reaction Steps

To 3-amino-6-(1-phenylcyclopropyl)pyridine-2(1H)-thione (106 mg, 0.437 mmol) was added 2-(tert-butoxycarbonyl)isoindoline-5-carboxylic acid (115 mg, 0.437 mmol), 1H-benzo[d][1,2,3]triazol-1-ol hydrate (67.0 mg, 0.437 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (84 mg, 0.437 mmol), and DMF (437 μL) before it was stirred at ambient T for 16 h. The reaction mixture was diluted with methanol before it was passed through a cartridge of cation exchange resinto give tert-butyl 5-(6-(1-phenylcyclopropyl)-2-thioxo-1,2-dihydropyridin-3-ylcarbamoyl)isoindoline-2-carboxylate after concentration. MS (ESI) m/z: Calculated: 487.2; Observed: 488.4 (M++H).
