Versuchsvorschrift

To a stirred solution of the material from Step 6 (3.27 g, 5.68 mmol) in dichloromethane (57 mL) were added 4-methylmorpholine N-oxide (0.8 g, 6.81 mmol), and activated 4 Å molecular sieves. After stirring at room temperature for 10 minutes, TPAP (0.1 g, 0.28 mmol) was added portionwise. The reaction mixture was stirred at room temperature for 3 hours, and then filtered through a silica gel plug. The filtrate was concentrated in vacuo to afford the title compound which was used directly at Step 8.
