| Product | 3,4-Dihydro-N-(2-propenyl)-2H-1-benzopyran-3-carboxamide | HCID 20383064 | — |
Reaction Steps
A solution of 5 g of 2A and 5.7 g of 2-propenamine in 50 ml of ethanol was refluxed for 6 days. Stripping of the solvent, followed by charcoal treatment of the product and recrystallization of the treated product from ether-hexane, gave 2, as white crystals, mp: 114.5°-115.5° C.
