Versuchsvorschrift

The 5-(3,3-dimethyl-but-1-ynyl)-3-[(3-hydroxy-1-(S)-methyl-propyl)-(trans-4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid TFA salt (100 mg, 0.239 mmol) and 4-chloro-7-methoxy-2-ethoxy-8-methyl-quinoline (301 mg, 1.195 mmol) were dissolved in DMSO (3 mL). To this solution tBuOK (107 mg, 0.956 mmol) was added in one portion at rt. The reaction was run at it for 15 min and then cooled in an ice bath. The reaction was quenched with a 20% (v/v) solution of acetic acid in water. The reaction was partitioned between water and EtOAc. The phases were separated and the organic phase was extracted with brine. The organic phase was extracted with brine and then concentrated. The residue was suspended in MeOH and remaining solids were removed by filtration. The filtrate was concentrated, suspended in MeOH and filtered again. The filtrate was clarified with a small amount of EtOAc and 5-(3,3-dimethyl-but-1-ynyl)-3-[[3-(2-ethoxy-7-methoxy-8-methyl-quinolin-4-yloxy)-1-(S)-methyl-propyl]-(4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid (29 mg, 16%) was isolated as the TFA salt by reverse phase HPLC.
