Sodium Bicarbonate → HCID 12069440, compound

Participants

Reaction Steps

In 4 ml of ethanol, 0.27 g of 5-carbamoyl-1,2,3,6-tetrahydropyridine trifluoroacetate and 0.36 g of 4-chloro-7-(4-isopropyl-2-methylthiophenyl)-2,5,6-trimethyl-7H-pyrrolo[2,3-d]pyrimidine were dissolved, and subsequently, 0.39 g of diisopiopylethylamine was added thereto. The reaction mixture was heated under reflux for 8.5 hours, and subsequently, a saturated aqueous solution of sodium hydrogencarbonate was poured therein to. The reaction mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and was then dried over anhydrous sodium sulfate. After the desiccant was filtered off, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:chloroform—methanol=60:1), followed by crystallization from a mixed solvent of ethyl acetate-diethyl ether to yield 0.12 g of 4-(5-carbamoyl-1,2,3,6-tetrahydropyridin-1-yl)-7-(4-isopropyl-2-methylthiophenyl)-2,5,6-trimethyl-7H-pyrrolo[2,3-d]pyrimidine.
