Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 10.0 g (0.033 mole) of α,α-bis(4-fluorophenyl)-4-piperidinemethanol, 4.5 g (0.033 mole) of 3-chloro-N,N-dimethylpropanamide, 14.0 g (0.132 mole) of anhydrous sodium carbonate and 0.3 g (0.002 mole) of potassium iodide in 100 ml of N,N-dimethylformamide was heated on a steam bath for 16 h. The mixture was poured into 2 L of water and extracted three times with 500 ml portions of ethyl acetate. The ethyl acetate fractions were combined, washed with water and brine, dried (MgSO4) and concentrated under reduced pressure to give a glass. Upon trituration with petroleum ether (30°-60° C.) the glass solidified to yield 13.2 g (100%) of a yellow solid. A portion of this solid was recrystallized from ethyl ether to give the title compound as a white solid, mp 134°-135° C. was heated on a steam bath for 16 h extracted three times with 500 ml portions of ethyl acetate washed with water and brine dried (MgSO4) concentrated under reduced pressure to give a glass

Procedure: N-tert-Butyl-2-(5-(difluoromethoxy)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (100 mg, 188 μmol), 3-chloro-N,N-dimethylpropanamide (25.6 mg, 188 μmol) and cesium carbonate (184 mg, 565 mmol) in dimethylformamide (2 mL) were heated in a microwave at 150° C. for 30 min. The mixture was cooled, partitioned between ethyl acetate and water, washed with water 3 times, dried and concentrated in vacuo. Purification by chromatography (silica, 24 g Analogix column, 0-100% ethyl acetate in hexanes) gave N-tert-butyl-2-(5-(difluoromethoxy)-1-(3-(dimethylamino)-3-oxopropyl)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (70 mg, 59%) as an off-white solid.
