Conditions

Temperature
100 °C

Procedure

The compound of step 2 (169 mg, 913 mmol) was suspended in acetic anhydride (1.75 ml) and heated at 100° C. for 3 h. The solution was cooled, water (2 ml) was added, and the mixture was stirred at 60° C. for 1 h. Upon cooling, crystals formed which were filtered off and dried in vacuo to give 120 mg of the title compound.
