Ethyl 2-amino-2-(5-bromo-3-chloropyridin-2-yl)acetate → (5-Bromo-3-chloropyridin-2-yl)methanamine hydrochloride
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl 2-amino-2-(5-bromo-3-chloropyridin-2-yl)acetate | HCID 71138503 | — |
| Solvent | Hydrochloric Acid | HCID 313 | — |
| Product | (5-Bromo-3-chloropyridin-2-yl)methanamine hydrochloride | HCID 71138342 | 182.4% |
Reaction Steps
A stirred solution of ethyl 2-amino-2-(5-bromo-3-chloropyridin-2-yl)acetate (0.5 g, 1.7 mmol) in 3 N HCl (25 mL) was heated at reflux for 4 h. The reaction mixture was washed with Et2O and water. The combined ether layer was concentrated under reduced pressure to afford the title compound as an off-white solid (400 mg, 65%): 1H NMR (400 MHz, CDCl3) δ 8.78 (s, 1H), 8.70 (br s, 2H), 8.45 (s, 1H), 4.56 (m, 2H); ESIMS m/z 221.15 ([M+H]+).
