Versuchsvorschrift

A suspension of 21z (0.73 g, 2.3 mmol) and N-(5-chloro-2-methoxyphenyl)thiourea (0.73 g, 2.53 mmol) in EtOH (25 mL) was refuxed for 30 min. Upon cooling, the product was collected by filtration and washed with cold ethanol to yield 22z as a pale yellow solid (0.40 g, 84%). Mp decomposition at 216° C. 1H NMR (600 MHz, DMSO-d6): δ 11.86 (br s, 1H) 9.93 (br s, 1H), 8.64 (d, J=2.4 Hz, 1H), 7.83 (s, 1H), 7.18 (s, 1H), 7.02 (d, J=8.4 Hz, 1H), 6.98 (dd, J=8.4 Hz, 2.4 Hz, 1H), 3.86 (s, 3H), 1.25 (s, 9H). 13C NMR (150 MHz, DMSO-d6): δ 176.7, 162.1, 158.9, 146.6, 140.2, 136.4, 130.5, 124.7, 124.2, 121.3, 117.3, 112.1, 91.0, 56.1, 38.8, 26.6. HRMS m/z (ESI) calcd. for C18H19ClN4O2S2 (M+H)+ 423.0711. Found 423.0713.
