実験手順

Compound 2a (12.3 g, 35.5 mmol) was dissolved in 150 mL of acetic anhydride and stirred at 60° C. for 4 hour. The mixture was slowly cooled to 4° C. under crystallization and the white crystals formed were filtered off, washed with cold acetic anhydride and dried under vacuum, to give 3a (10.8 g, 32.8 mmol, 93%). mp: 214.0° C.
