Versuchsvorschrift

To a solution of tert-butyl 5-[(2,5-dichloropyrimidin-4-yl)amino]-hexahydrocyclopenta[c]pyrrole-2(1H)-carboxylate (1.10 g, 2.95 mmol) and 1-(cyclopropylmethyl)pyrazol-4-amine (38.5 mg, 0.28 mmol) in dioxane (10 mL) was added 2,2,2-trifluoroacetic acid (61.8 mg, 0.54 mmol). The reaction mixture was stirred at 100° C. overnight, then adjusted to pH=10 with a saturated Na2CO3 solution, and extracted with EtOAc (100 mL×3). The combined organic phases were washed with brine (100 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/PE (v/v)=1/2) to give the title compound as a pale yellow solid (0.36 g, 26%).
