Reaction Steps

A solution of methyl {3-[N-({6-amino-5-[(3-{[(1,3-dimethyl-1H-pyrazol-5-yl)carbonyl]amino}phenyl)ethynyl]pyridin-3-yl}carbonyl)-S-methylsulfonimidoyl]phenyl}acetate (13 mg, 0.021 mmol) and 1.0M NaOH (0.171 ml, 0.171 mmol) in 2.0 ml MeOH and 0.1 ml H2O was stirred at room temperature for 1 hour 10 minutes. The pH of the mixture was adjusted to pH 4 using 10% HCl, brine added, and the aqueous extracted with EtOAc. The combined EtOAc layers were washed with brine, dried with anhydrous Na2SO4 and rotary evaporated. The white solid was triturated with hot EtOAc to give white solid (11 mg, 92%).
