Procedure

1.65 g (3.30 mmol) of (RS)—S-[4-({5-bromo-4-[(R)-(2-hydroxy-1,2-dimethylpropyl)amino]pyrimidin-2-yl}amino)phenyl]-N-(ethoxycarbonyl)-S-methyl sulfoximide in 6.5 ml of ethanol is mixed with 19.1 ml (6.69 mmol) of a 0.35 molar solution of NaOEt in ethanol and stirred under reflux for 5 hours. The batch is stirred overnight at room temperature and then added to a saturated NaCl solution. It is extracted with ethyl acetate, and the combined organic phases are dried (Na2SO4), filtered and concentrated by evaporation. The remaining residue is purified by chromatography (DCM/EtOH 9:1). 0.95 g (2.22 mmol, corresponding to 67% of theory) of the product is obtained.
