Examples
Embodiment 1
[0494] 1-(5-{5-chloro-2-[1-(2-morpholin-4-ylethyl)-1H-pyrazol-4-yl]-1H-pyrrolo[2,3-b]pyridine -4-yl}-1,3-thiazol-2-yl)cyclobutanol
Embodiment 1A
[0496] 1-(thiazol-2-yl)cyclobutanol
[0497] To a cold (-78°C) solution of thiazole (6.59ml, 93mmol) in tetrahydrofuran (238ml) was added n-butyllithium (58.0ml, 93mmol) dropwise. The reaction was stirred for 15 minutes and cyclobutanone (5.0 g, 71.3 mmol) was added via syringe. The reaction was stirred for 10 minutes then quenched by the addition of saturated aqueous bicarbonate solution. The cooling bath was removed and the reaction was allowed to warm to room temperature. Ethyl acetate was added and the layers were separated. The aqueous layer was extracted with additional ethyl acetate (2x). The combined organics were dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give the title compound which was used in the next step without further purification. MS ESI(+) m / z 156 [M+H] + .
Embodiment 1B
[0499] 2-(1-(Methoxymethoxy)cyclobutyl)thiazole
[0500]To a cold (0 °C) suspension of sodium hydride (1.07 g, 44.4 mmol) in N,N-dimethylformamide (50 mL) was added 1-(thiazol-2-yl)cyclobutanol (for Example 1A) (5.3 g, 34.1 mmol) in N,N-dimethylformamide (18 ml). After 0.5 hour, chloro(methoxy)methane (3.89 mL, 51.2 mmol) was added and the reaction was stirred for 16 hours. The reaction was quenched by adding ether and water. The layers were separated and the aqueous layer was extracted with additional ether. The combined organics were dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography on silica gel, eluting with a gradient of 0 to 50% ethyl acetate in hexanes, to give the title compound. MS ESI(+) m / z 200 [M+H] + .
