Versuchsvorschrift

The urea was synthesized from 2-(2-thiophene sulfonyl amino) aniline (1 mmol) and 2-bromo phenyl isocyanate (1 mmol) by general Method B. It was purified by dilution with methylene chloride and precipitation with hexane. Filtering afforded the desired compound (0.29 g, 64%). EI-MS m/z 450 (M-H)-
