Versuchsvorschrift

To a mixture of 244a (900 mg, 2.7 mmol) and triethylamine (810 mg, 8.1 mmol) in dichloromethane (30 mL) was added acetyl chloride (630 mg, 8.1 mmol) dropwise. The reaction mixture was stirred at 30° C. for 1 h. It was then concentrated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with dichloromethane to afford 244b as white solid (900 mg, 90%). MS-ESI: [M+H]+ 374.2
