실험 절차

To a suspension of tert-butyl 5-[(2,5-dichloropyrimidin-4-yl)amino]-hexahydrocyclopenta[c]pyrrole-2(1H)-carboxylate (373.0 mg, 1.00 mmol) and 1-methylimidazol-4-amine (341.8 mg, 3.52 mmol) in dioxane (10 mL) were added Pd(OAc)2 (52.0 mg, 0.23 mmol), BINAP (125.0 mg, 0.19 mmol) and Cs2CO3 (647.2 mg, 1.99 mmol). The reaction mixture was stirred at 150° C. under microwave for 2 h and concentrated in vacuo. The residue was purified by silica gel column chromatography (MeOH/DCM (v/v)=1/50) to give the title compound as a pale yellow solid (0.21 g, 48%).
