YieldReaction ConditionsOperation in experiment
85% With sodium hydroxide In methanol EXAMPLE 3
Preparation of alpha-methoxy-4-hydroxyacetophenone
2 g of alpha-bromo-4-hydroxyacetophenone are dissolved in 11 g of methanol.
30 g of a saturated solution of sodium hydroxide in methanol (1 g NaOH/ 4.2 ml methanol) is added dropwise to the alpha-bromo-4-hydroxyacetophenone solution.
After the addition is complete, the solution is added to 30 g of ice and acidified to pH 6.
Alpha-methoxy-4-hydroxyacetophenone precipitates out and is filtered and dried to a greenish yellow product in about 85percent yield; the product is determined by 1-H-NMR to be substantially pure.
