Reaction Steps

0.6 g of 2-(1-hydroxy-2'methoxy-5'-bromobenzyl)pyrazine were dissolved in 15 ml of methylene chloride. At 0° C., 0.2 g of NaH were added, resulting in the evolution of a gas and formation of a precipitate. 0.4 ml of trimethylacetyl chloride were added in one portion. The reaction mixture was stirred at room temperature overnight. The solvent was then stripped from the reaction mixture, and the residue was extracted with ice water and methylene chloride. The methylene chloride layer was washed with water, dried (MgSO4), filtered and stripped of the solvent to yield 0.9 g of 3-(1-trimethylacetoxy-2'-methoxy-5'-bromobenzyl)-pyrazine.
