Procedure

The Sulfonamide of Step One, 3-phenylsulfamoylthiophene-2-carboxylic acid methyl ester, was dissolved in dry dichloromethane and N,N-diisopropyl ethylamine. The resulting mixture was chilled to 0° C. prior to the addition of bromomethyl methyl ether. The reaction mixture was stirred over night at room temperature. The mixture was partitioned between dichloromethane and aqueous HCl (2N). The organic layer will then be washed one time with saturated sodium chloride solution and dried over sodium sulfate, followed by concentration to dryness under reduced pressure to give the desired product, 3-(N-methoxymethyl-N-phenylsulfamoyl)thiophene-2-carboxylic acid methyl ester (3 g, quantitative).
