Procedure

Acetic anhydride (14.25 ml) was added dropwise to a mixture of intermediate (2-a) (36.6 g) in acetic acid (500 ml), stirred at room temperature. The reaction mixture was stirred for 15 minutes at room temperature. The reaction mixture was poured out into water (500 ml). The precipitate was filtered, washed with water, then dried, yielding 39.29 g (92.6%) of N-(7-iodo-1,3-benzodioxol-4-yl)acetamide (intermediate 2-b).
