Yield:93-15-2 95%

Reaction Conditions:

with potassium carbonate in acetone at 20; for 12 h;

Steps:

2.1.1. Methyl-eugenol (2)
To a solution of the eugenol (1) (4.1 g, 25 mmol) in acetone (25 mL), K2CO3 (10.2 g, 75 mmol) and CH3I (10.5 g, 75 mmol) were added. After 12 h, the reaction mixture was filtered and the solvent was removed to afford product 2 in 95% of yield (4.227 g), brownish oil.
