Sodium hydride → 4-(3-Methoxy-phenyl)-7-[2-(4-methyl-piperazin-1-yl)-pyridin-4-yl]-2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine

Participants

Reaction Steps

Sodium hydride (108 mg, 60% mineral oil dispersion, 2.72 mmol) was placed in a dried flask under a nitrogen atmosphere, followed by sequential addition of anhydrous tetrahydrofuran (10 ml) and 2-(4-methylpiperazin-1-yl)pyridin-4-ylamine (62 mg, 0.32 mmol) with a syringe, and the resulting mixture was heated to reflux for 2 hours. 4-[4-chloro-5-(2-chloroethyl)-6-(3-methoxyphenyl)-pyrimidin-2-yl]morpholine (100 mg, 0.27 mmol) was added, followed by heating to reflux for 16 hours. The reaction mixture was cooled, which was subsequently added dropwise slowly onto ice water, followed by extraction twice with ethyl acetate (10 ml). The organic layer was washed with brine (10 ml), and dried over sodium sulfate, followed by distilling off under reduced pressure, to obtain a crude product as a red oil (107 mg).
