Versuchsvorschrift
Following the general procedure for urea formation outlined in example 15, 4-chloro-2-hydroxy-3-(1-oxidothiomorpholinosulfonyl)aniline (117 mg, 0.35 mmol) and 2,3-dichlorophenylisocyanate (72 mg, 0.38 mmol) were coupled to form the desired urea (79 mg, 44%). 1H NMR (DMSO-d6): δ 9.34 (s, 1H), 9.27 (s, 1H), 8.28 (d, 1H), 8.05 (m, 1H), 7.32 (m, 2H), 7.21 (d, 1H), 3.75 (m, 2H), 3.65 (m, 2H), 2.89, (m, 4H).
