Several drops of triethylamine were added, then 3-azabicyclo[3.1.0]hexan hydrochloride salt (42 mg, 0.35 mmol) was added. The reaction mixture was heated to reflux overnight. The solvent was removed by rotary evaporation, and water was added, followed by extraction with DCM. The organic phase was dried over sodium sulfate and purified by silica gel column chromatography (DCM/methanol=20/1 to 10/1). 2-(3-azabicyclo[3.1.0]hexan-3-yl)-4-((3-chloro-4-methoxybenzyl)amino)-N-(pyrimidin-2-ylmethyl)pyrimidine-5-formamide as a white solid was obtained (40 mg, 39% yield).
