| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanol | HCID 887 | — |
| Reactant | (3,4-Dimethoxyphenyl)acetic acid | HCID 7139 | — |
| Catalyst | Sulfuric Acid | HCID 1118 | — |
| Product | Benzeneacetic acid, 3,4-dimethoxy-, methyl ester | HCID 85213 | 96% |
Reaction Steps
To a solution of 2-(3,4-dimethoxyphenyl)acetic acid (25.0 g, 127.4 mmol) in MeOH (100 mL) in a 500 mL round-bottomed flask equipped with a magnetic stirrer was added a catalytic amount of sulfuric acid (around 10 drops) and the mixture was stirred overnight under reflux. After cooling to RT, MeOH was removed at 40° C. under vacuum and the product was taken up in CH2Cl2 (250 mL), washed with water (5×20 mL), brine (20 mL), dried over Na2SO4, filtered, and concentrated under vacuum to give methyl 2-(3,4-dimethoxyphenyl)acetate SLA 28134 as an orange oil (25.77 g, 96% yield).
