Reaction Steps

To a suspension of tert-butyl 4-((2-chloropyrimidin-4-yl)(methyl)amino)-2-azaspiro[4.4]nonane-2-carboxylate (0.34 g, 0.93 mmol) in n-BuOH (5.0 mL) was added 1-methyl-1H-pyrazol-4-amine hydrochloride (0.25 g, 1.85 mmol) and DIPEA (0.48 g, 3.71 mmol). The mixture was stirred in a sealed tube and heated to 150° C. overnight, then concentrated in vacuo.
