Procedure

(1Z)-N′-hydroxy-2-(2-thienylsulfonyl)ethanimidamide (0.250 g) with dihydro-2,5-furandione (0.114 g) in dimethylformamide (0.2 ml) was heated at 120° C. for 2 hours. The reaction was allowed to cool and triturated with diethyl ether and filtered to leave 3-{3-[(2-thienylsulfonyl)methyl]-1,2,4-oxadiazol-5-yl}propanoic acid (0.332 g).
