Potassium Bicarbonate → HCID 86623407, compound

Participants

Reaction Steps

A solution of 1.9 g (0.011 mole) of 3-cyclobutylaminopropanoic acid ethyl ester in 7 mL of acetonitrile was added dropwise to a mixture of 1.74 g (0.09 mole) of 2,4-dichloro-5-nitro-pyrimidine and 2.07 g (0.021 mole) of potassium bicarbonate and 20 mL of acetonitrile at ambient temperature over 45 mins. The mixture was stirred for 2.5 hours, then diluted with 45 mL of ethyl acetate. The mixture was filtered, concentrated under reduced pressure and the residue purified by silica gel chromatography, eluting with hexanes-ethyl acetate (100:0-90:10) to give 1.7 g of 3-[(2-chloro-5-nitro-pyrimidin-4-yl)-cyclobutyl-amino]-propanoic acid ethyl ester (IV-23).
