In THF (10 mL) were dissolved 2-(3-azabicyclo[3.1.0]hexan-3-yl)-4-((3-chloro-4-methoxybenzyl)amino)-pyrimidine-5-carboxylic acid (150 mg, 0.40 mmol), 2-morpholinylethylamine (59 mg, 0.45 mmol) and triethylamine (101 mg, 1 mmol). The reaction mixture was cooled in an ice bath and HATU (266 mg, 0.70 mmol) was added. The reaction was conducted at ambient temperature for 18 h. The reaction mixture was concentrated, followed by addition of water and extraction with ethyl acetate. The organic phase was dried, concentrated, and purified by silica gel column chromatography (DCM methanol=20/1) to give 2-(3-azabicyclo[3.1.0]hexan-3-yl)-4-((3-chloro-4-methoxybenzyl)amino)-N-(2-morpholinylethyl)pyrimidine-5-formamide (71 mg, 36.5% yield).
