Aluminium lithium hydride → Azd8055

Participants

Reaction Steps

A solution of lithium aluminium hydride (2M solution in THF, 1.01 mL, 2.01 mmol) was added to a solution of methyl 5-{2,4-bis[(3S)-3-methylmorpholin-4-yl]pyrido[2,3-d]pyrimidin-7-yl}-2-methoxybenzoate (1.47 g, 2.68 mmol) in THF (19.8 mL) at 0° C. under an atmosphere of nitrogen. After 60 minutes, further lithium aluminium hydride (2M solution in THF, 0.67 mL, 1.34 mmol) was added and the solution allowed to stir at RT for 900 minutes. The resulting solution was quenched by the addition of water (11.76 mL) and extracted with ethyl acetate (22 mL). On evaporation of the ethyl acetate, 1.2 g of (5-{2,4-bis[(3S)-3-methylmorpholin-4-yl]pyrido[2,3-d]pyrimidin-7-yl}-2-methoxyphenyl)methanol (6) is obtained as a yellow solid.
