Reaction Steps

According to GWP 6, (RS)-S-(3-{[(6-bromo-4-{[(S)-2-hydroxypropyl]amino}quinazolin-7-yl)oxy]methyl}phenyl)-N-(ethoxycarbonyl)-S-methylsulphoximide (39 mg, 0.073 mmol) is dissolved in ethanol (5 mL), admixed with sodium ethoxide (18 mg, 0.26 mmol) and stirred at 60° C. for 6 hours. The reaction solution is admixed with saturated sodium bicarbonate solution and extracted with ethyl acetate. Drying of the organic phase over sodium sulphate and removal of the solvent and also chromatographic purification of the residue (silica gel, dichloromethane/methanol: 0→10% methanol) gives the desired product in 86% yield (29 mg).
