2-(4-fluorophenoxy)ethanamine;hydrochloride

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Next, to a solution of [2-(4-fluorophenoxy)ethyl]carbamic acid tert-butyl ester (7.0 g, 27.4 mmol) in dioxane (20 mL) cooled in an ice bath was added 4N—HCl in dioxane (100 mL) dropwise. The mixture was stirred at 0° C. for 2 hours, and at room temperature for 16 hours. The precipitates were filtered, washed with diethylether, and dried under reduced pressure to yield 2-(4-fluorophenoxy)ethylamine HCl salt (4.24 g, 80.7% yield). at room temperature for 16 hours The precipitates were filtered washed with diethylether dried under reduced pressure

実験手順: Compound A (200 mg, 813 mmol), 2-(4-fluorophenoxy)ethylamine hydrochloride (466 mg) and sodium hydrogencarbonate (683 mg) were added to DMSO (6 ml), and the mixture was stirred at 100° C. for 27 hr. After stirring, the reaction mixture was added to cold water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and concentrated, and the residue was washed by suspending in ethyl acetate to give the object compound of 2-(2-(4-fluorophenoxy)ethylamino)-6-(5-methyl-1H-pyrazol-3-ylamino)-4-methylnicotinonitrile (38 mg). After stirring the mixture was extracted with ethyl acetate The organic layer was washed with saturated brine concentrated the residue was washed
