Participants

Reaction Steps

40 mg (0.063 mmol) of 2-{4-[7-({[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methyl}sulfanyl)-6-cyano-2-ethyl-4-oxo-3,4-dihydropyrido[2,3-d]pyrimidin-5-yl]phenoxy}ethyl propanoate were initially charged in 4 ml of a dioxane/water mixture 2:1, 3 mg (0.127 mmol) of lithium hydroxide were added and the mixture was stirred at RT. After 3 h, the reaction mixture was purified by preparative HPLC (mobile phase gradient: acetonitrile/water 10:90→95:5, with 0.1% TFA added). This gave 27 mg (70% of theory) of the target compound.
