Procedure

In THF (10 mL) were dissolved 4-((3-chloro-4-methoxybenzyl)amino)-2-(methyl sulfinyl)-N-(pyrimidin-2-ylmethyl)pyrimidine-5-formamide (152 mg, 0.34 mmol) and 2-methyl-2,7-diazaspiro[3.5]nonane (70 mg, 0.50 mmol). Then triethylamine (68 mg, 0.67 mmol) was added dropwisely. The reaction was conducted at ambient temperature for 4 h. The solvent was removed by rotary evaporation, followed by addition of water and extraction with DCM. The organic phase was dried over sodium sulfate and purified by silica gel column chromatography (DCM/methanol=20/1) to give 4-((3-chloro-4-methoxybenzyl)amino)-2-(7-methyl-2,7-diazaspiro[3.5]nonan-2-yl)-N-(pyrimidin-2-ylmethyl)pyrimidine-5-formamide as a white solid (16 mg, 9% yield).
