실험 절차

Potassium hydroxide solution (1.7 mL, 3.10 mmol) was added to a solution of 5-{2,4-bis[(3S)-3-methylmorpholin-4-yl]pyrido[2,3-d]pyrimidin-7-yl}-2-methoxybenzyl pivalate (172 mg, 0.30 mmol) in THF (6.9 mL) and methanol (1.7 mL) at RT under an atmosphere of nitrogen. After 240 minutes, HPLC analysis showed complete disappearance of the starting material. The reaction was maintained at RT overnight (for convenience) and aqueous citric acid (20% w/v, 2 mL) was added followed by methylene chloride (15 mL). The upper aqueous layer was extracted with two further extractions of methylene chloride (2×15 mL) and the organic layers combined. Evaporation of the methylene chloride afforded (5-{2,4-bis[(3S)-3-methylmorpholin-4-yl]pyrido[2,3-d]pyrimidin-7-yl}-2-methoxyphenyl)methanol (6) as a yellow solid (133 mg).
