Reaction Steps

To a solution of tert-butyl 3-[(2,5-dichloropyrimidin-4-yl)amino]-9-azaspiro[5.5]undecane-9-carboxylate (501.5 mg, 1.21 mmol) and 2-(4-aminopyrazol-1-yl)ethanol (306.5 mg, 2.411 mmol) in propan-2-ol (6 mL) was added a solution of HCl in EtOAc (1 mL, 4 mmol). The mixture stirred in a sealed tube under the microwave radiation at 140° C. for 1 h and then concentrated in vacuo. The residue was purified by silica gel column chromatography (MeOH/DCM (v/v)=1/100 to 1/20 to 1/7) to give the product as a light yellow solid (500.0 mg, 0.9881 mmol, 81.85%).
