Versuchsvorschrift

1-(4-Methoxy-phenyl)-cyclopropanecarboxylic acid (2.18 g, 11.4 mmol) and 4-phenyl-thiazol-2-ylamine (2.00 g, 11.4 mmol) were dissolved in acetonitrile (50 mL) containing triethylamine (3.17 mL, 22.8 mmol). Benzotriazol-1-yloxy tris(dimethylamino)-phosphonium hexafluorophosphate (BOP, 4.95 g, 11.4 mmol) was added and the solution was allowed to stir for 64 hours. The reaction mixture was evaporated to dryness and purified by column chromatography on silica gel using a gradient of 5-20% ethyl acetate in hexanes. The pure fractions were combined and evaporated to dryness to yield a white solid (1.9 g, 5.43 mmol, 47.5%). ESI-MS m/z calc. 350.1. found 351.1 (M+1)+. Retention time of 3.68 minutes. 1H NMR (400 MHz, CD3CN) δ 1.27 (q, J=3.6 Hz, 2H), 1.66 (q, J=3.6 Hz, 2H), 3.87 (s, 3H), 7.04 (m, 2H), 7.40 (m, 6H), 7.82 (m, 2H), 8.79 (s, 1H).
