Diisopropylethylamine → HCID 73214617, compound

Participants

Reaction Steps

In DCM (30 mL) were dissolved 4-((3-chloro-4-methoxybenzyl)amino)-2-(methylsulfinyl)-N-(pyrimidin-2-ylmethyl)pyrimidine-5-formamide (429 mg, 0.96 mmol) and DIEA (0.22 mL, 1.12 mmol). 2-Methyl-2,7-diazaspiro[4.4]nonane (154 mg, 1.1 mmol) was then added. The reaction was conducted at ambient temperature overnight. The solvent was removed by rotary evaporation, followed by addition of water and extraction with ethyl acetate. The organic phase was dried over sodium sulfate and purified by silica gel column chromatography (DCM/methanol=20/1 to 10/1) to give a white solid (20 mg, 4% yield).
