Reaction Steps

A mixture of 7-[(cyclopropylmethyl)(2-thienylsulfonyl)amino]-1-(methoxymethyl)-1H-indole-2-carboxamide (390 mg), oxalic acid dihydrate (351 mg), methanol (15 mL) and water (15 mL) was stirred at 70° C. for 1 hr, and further at 90° C. for 14 hr. The reaction mixture was allowed to cool to room temperature. The resulting crystals were collected by filtration, washed successively with water, a diethyl ether-hexane mixture and hexane, and dried to give the title compound (286 mg, yield 81%) as crystals. melting point 229-231° C.
