Versuchsvorschrift

To 0° C. flask charged with 65.B (2.85 g, 11.7 mmol) was added a solution of BBr3/CH2Cl2 (1.0 M, 25 mL). The solution was allowed to warm to rt and stirred for 45 mins. The resulting mixture was treated with MeOH (7 mL), neutralized with solid NaHCO3 to PH=7 and concentrated under reduced pressure. Purification of the residue by flash chromatography on silica gel using 0-10% of MeOH/CH2Cl2 for elution gave the title product 65.C as solid (1.83 g, 68%).
