Potassium tert-butoxide → HCID 86677571, compound

Participants

Reaction Steps

To a solution of 2-[2-(2-chloro-pyrimidin-5-ylamino)-ethyl]-2-ethyl-4-methoxy-butyric acid methyl ester (0.083 g, 0.277 mmol) in THF (6 mL) was added a solution of potassium t-butoxide (1 M in THF) (0.5 mL), and the solution was allowed to stir at room temperature for 1 hour. An additional 0.5 mL of potassium t-butoxide (1 M in THF) was added and stirred for 2 hours. The reaction was still not complete, thus 0.75 mL of potassium t-butoxide (1 M in THF) was added and stirred for 4 hours. The reaction mixture was then diluted with ethyl acetate (20 mL), quenched with water (3 mL). The aqueous layer was extracted with EtOAc (2×20 mL). The combined organics were washed with brine, and concentrated under vacuum to afford 0.07 (95%) of title compound.
