実験手順
To a solution of isopropyl 2-[2-cyano-4-fluoro-3-[[2-fluoro-5-(3-fluorophenyl)phenyl]methylamino]phenoxy]acetate (220 mg, 0.48 mmol, 1 eq) in a mixture of THF (10 mL) and water (10 mL) was added LiOH (20 mg, 0.96 mmol, 2 eq). The reaction was stirred for 3 h then the THF removed in vacuo. The aqueous solution that remained was acidified to pH 4 with 3M HCl and the aqueous layer was extracted with EtOAc. The combined organic extracts were washed with brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was triturated with a mixture of 2-methoxy-2-methylpropane (5 mL) and petroleum ether (20 mL) to give the desired product as an off-white solid (110 mg, 56%).
