4-Chlorobenzylamine → Diethyl 2-(((4-Chlorobenzyl)amino)carbonyl)malonate
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Chlorobenzylamine | HCID 66036 | — |
| Reactant | Triethyl methanetricarboxylate | HCID 80471 | — |
| Product | Diethyl 2-(((4-Chlorobenzyl)amino)carbonyl)malonate | HCID 22397146 | 30.5% |
Reaction Steps
Triethyl methanetricarboxylate (2.32 g) and 4-chlorobenzylamine (1.42 g) are stirred at room temperature for 16 h. Insoluble material is filtered off and the filtrate is purified by column chromatography (hexanes/acetone, 5/1) to give 1 g (12%) of the title compound as an oil which slowly solidifies. Physical characteristics: MS (ESI+) m/z 330 (M+H)+. 1H NMR (CDCl3) δ7.70, 7.31, 7.26, 4.48, 4.38, 4.28, 1.30.
