Product 1

HCID 78208Thiophen-2-acetamideYield 64%

Procedure

To a mixture of concentrated NH4OH (100 mL) and ice was added 2-thiopheneacetyl chloride (13.0 g, 80.9 mmol). The desired compound crystallized from the reaction mixture. Recrystallization from hot water gave 2-thiopheneacetamide (8.08 g, 64% yield) as white crystals. mp 146°-147° C.
