Versuchsvorschrift

To a stirred mixture of N-(5,6-dihydrospiro[benzo[b]thiophen-7(4H), 2'-[1,3]dithiolan]-4-yl)formamide (1.5 g), acetonitrile (20 ml) and water is added calcium carbonate (1.65 g) and mercuric chloride (3.0 g). The mixture is stirred at room temperature for 35 minutes and acetonitrile is added. The solid is filtered and washed with acetonitrile. The filtrate (100 ml) is evaporated to dryness to afford the title compound.
