| Reactant | Dihydrocoumarin | HCID 660 | — |
| Reactant | Diethylamine | HCID 8021 | — |
| Product | N,N-diethyl-3-(2-hydroxyphenyl)propanamide | HCID 45803915 | 113.8% |
Reaction Steps
Diethylamine (98.5 g) and dihydrocoumarin (20.0 g) were refluxed for 4 hours. Excess diethylamine was removed in vacuo to leave 34.0 g of N,N-diethyl-3-(2-hydroxyphenyl) propionamide. 1H NMR (CDCl3): 7.26-7.03 (m, 2H), 6.91 (dd, 1H), 6.81 (td, 1H), 3.37 (quartet, 2H), 3.26 (quartet, 2H), 2.95 (m, 2H), 2.71 (m, 2H), 1.10 (quartet, 6H).
