Reaction Steps

To a solution of ethyl 2-(4-chloro-5-cyclopropyl-2-hydroxyphenylamino)acetate (290 mg, 0.89 mmol) in of 4:1 mixture of tetrahydrofuran and water (30 mL) at RT, LiOH.H2O (226 mg, 5.34 mmol) was added and the resulting mixture was stirred for 2 h at 60° C. The mixture was acidified with aqueous HCl (1N) to adjust the pH to 3-5 and then extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to afford the product (100 mg, 47% yield). 1H NMR (400 MHz, DMSO-d6) δ: 9.64 (s, 1H), 6.66 (s, 1H), 5.96 (s, 1H), 3.81 (s, 2H), 1.89-1.96 (m, 1H), 0.84-0.87 (m, 2H), 0.54-0.56 (m, 2H).
