Sodium hydride → HCID 9951280, compound

Participants

Reaction Steps

To a suspension of 5-methanesulfonyl-2-(2-pyrimidinyl)-1H-pyrrolo[2,3-b]pyridine (150 mg) in N,N-dimethylformamide (5.5 ml), 60% sodium hydride (32.8 mg) was added at 0° C. under nitrogen atmosphere and the mixture was stirred at the same temperature for 30 minutes. Subsequently, to the mixture was added cyclohexylmethyl bromide (154 mg) at 0° C. and the mixture was stirred at 60° C. for 2 hours, followed by addition of cyclohexylmethyl bromide (77 mg) and stirring of the mixture at the same temperature for 1 hour. Further, to the mixture was added cyclohexylmethyl bromide (77 mg) and the mixture was stirred at 60° C. for 15 hours. Subsequently, the reaction solution was poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with chloroform. The organic layer was washed with a saturated aqueous NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (methanol:chloroform=1:20) and further recrystallized, (chloroform/hexane) to obtain 109 mg of the desired product as a white needle-like crystal.
