Chloroacetyl chloride → HCID 178459413, compound

Participants

Reaction Steps

A solution of isopropyl 2-[(trans-4-hydroxycyclohexyl)amino]-4-oxo-4,5-dihydrofuran-3-carboxylate (0.10 g, 0.44 mmol) which similarly prepared according to the procedure described in the Example 74, Third step using diisopropyl malonate and chloroacetyl chloride, and trans-4-aminomethylcyclohexanol (0.056 mg, 0.49 mmol) in 2-propanol (1.0 mL) was stirred at ambient temperature for 20 h. To this reaction mixture, 7-azaindole-3-carboxaldehyde (0.065 g, 0.44 mmol) and L-proline (0.0050 g, 0.044 mmol) were added then the mixture was refluxed for further 1.5 days. The precipitate was collected by filtration, washed with hot ethanol. The solid was washed with hexane then dried to afford isopropyl 5-[(1H-pyrrolo[2,3-b]pyridin-3-yl)methylene]-2-[(trans-4-hydroxycyclohexyl)amino]-4-oxo-4,5-dihydrofuran-3-carboxylate as solid (0.0076 g, y. 4%).
