Vorschrift

4-(2-Methylthiazol-4-yl)aniline (19 mg, 0.10 mmol) and 1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxylic acid (20.6 mg, 0.100 mmol) were dissolved in acetonitrile (1.0 mL) containing triethylamine (42 μL, 0.30 mmol). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (42 mg, 0.11 mmol) was added to the mixture and the resulting solution was allowed to stir for 16 hours. The crude product was purified by reverse-phase preparative liquid chromatography to yield 1-(benzo[d][1,3]dioxol-5-yl)-N-(4-(2-methylthiazol-4-yl)phenyl)cyclopropane-carboxamide. ESI-MS m/z calc. 378.1. found; 379.1 (M+1)+; Retention time 2.72 minutes. 1H NMR (400 MHz, DMSO-d6) δ 1.04-1.10 (m, 2H), 1.40-1.44 (m, 2H), 2.70 (s, 3H), 6.03 (s, 2H), 6.88-6.96 (m, 2H), 7.01 (d, J=1.4 Hz, 1H), 7.57-7.61 (m, 2H), 7.81-7.84 (m, 3H), 8.87 (s, 1H).
