Reaktionsschritte
Bromine (80 g, 0.5 mol) is added dropwise to a solution of 1,1-dimethoxy-propan-2-one 205 (59 g, 0.5 mol) in anhydrous methanol (400 mL) at 0° C. and the solution is continued stirring at room temperature for 48 h. The solvent is removed under reduced pressure and the residue is dried in vacuo and used without further purification.
