Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-((2-Chloro-4-nitrophenoxy)methyl)pyridine | HCID 17469433 | — |
| Catalyst | Platinum | HCID 23939 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | 3-Chloro-4-(2-pyridylmethoxy)aniline | HCID 16781212 | 80% |
Reaction Steps
2-(2-Chloro-4-nitro-phenoxymethyl)-pyridine (2.4 g, 9.07 mmol) is suspended in MeOH (30 ml) and treated wet 5% Pt/C (Degussa type, Aldrich, 0.8 g). The flask is flushed with hydrogen gas from a balloon and the reaction mixture is stirred under hydrogen atmosphere until reaction is complete by TLC (ca 2 hours). The reaction mixture is filtered through a Celite plug and the solvent is removed under reduced pressure. The crude product is redissolved in DCM, dried (MgSO4) and concentrated to yield 1.7 g (7.23 mmol, 80%) of the desired product.
