Reaktionsschritte
To a solution of 1-hydroxymethyl-2-methoxy-benzene (28.7 g, 0.207 mol) in CH2Cl2 (574 mL) at 0° C. under nitrogen was added slowly PBr3 (13.66 mL, 0.145 mol). After stirring for an additional 1.5 hours, MeOH (13.66 mL) was added and stirred for 5 minutes. To this mixture was added dropwise 10% Na2CO3 (2 mL) solution and stirred for 5 minutes. The mixture was then washed with 10% Na2CO3 (50 mL, 2×) and brine (100 mL). It was dried over MgSO4, and filtered. The filtrate was removed under vacuum to give an oil (40 g) of 1-bromomethyl-2-methoxy-benzene. This material was used without purification.
