Versuchsvorschrift

In a round bottom flask under argon was placed 2-[4-(2-chloro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-5,5-dimethyl-hexanoic acid (32 mg, 0.091 mmol) in dichloromethane (3 mL). To this mixture was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (20 μL, 0.10 mmol) and 1-hydoxybenzotriazole (13 mg, 0.096 mmol) and stirred at 25° C. for 2 h. After this time period, 1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-ylamine (prepared as in Example 49, 21 mg, 0.109 mmol) was added and stirred for 16 h at 25° C. After this time, the mixture was diluted with dichloromethane (10 mL) and washed with a 1N aqueous hydrochloric acid solution (10 mL), water (10 mL) and a saturated aqueous sodium bicarbonate solution (10 mL), dried over magnesium sulfate, filtered and concentrated in vacuo. Purification by AnaLogix IntelliFlash flash chromatography (4 g column, 30% ethyl acetate/hexanes to 100% ethyl acetate/hexanes) afforded 2-[4-(2-chloro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-5,5-dimethyl-hexanoic acid [1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-yl]-amide (14 mg, 29%) as a colorless oil.
