Versuchsvorschrift

(S)-1-(4-Guanidino-phenyl)-pyrrolidine-2-carboxylic acid dimethylamide (Method 54; 0.5 g, 1.82 mmol) and (2Z)-3-(dimethylamino)-2-fluoro-1-(1-isopropyl-2-methyl-1H-imidazol-5-yl)prop-2-en-1-one (Method 14; 0.2 g, 0.83 mmol) were heated at reflux in butanol (7 ml) overnight. LCMS indicated only 7% product. The reaction was transferred to a microwave tube and heated at 200° C. for 2 hours. LCMS indicated 15% starting material and mainly product. The solvent was removed in vacuo and chromatographed. The product was purified by HPLC and the required fractions were combined and basified with K2CO3 (0.5 g), extracted with DCM (2×50 ml), dried and the solvent removed in vacuo to yield a yellow solid (101 mg, 31%).
