| Reactant | (3-Methoxy-4-nitrophenyl)(dimethyl)phosphane oxide | HCID 67052712 | — |
| Catalyst | Palladium | HCID 23938 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | (4-Amino-3-methoxyphenyl)dimethylphosphine oxide | HCID 67052699 | 100.4% |
Reaction Steps
To a solution of (3-methoxy-4-nitrophenyl)(dimethyl)phosphane oxide (0.1 g, 0.44 mmol) in 5 mL of EtOH was added 10% weight of palladium on carbon (0.2 g). The mixture was purged with argon, and hydrogenated under 30 psi for 2 h. The mixture was passed through Celite to a flask containing HCl in ethanol. Concentration of the filtrate gave the final product (0.088 g, 86% yield). MS/ES+: m/z=199.
