Procedure

To a solution of methyl (5-{3-[[5-fluoro-2-(4-methoxyphenyl)-4-pyrimidinyl](methyl)amino]propoxy}-1H-indol-1-yl)acetate (Example 86, 0.1 g, 0.20 mmol) in methanol (2 mL), THF (2.00 mL), and water (1.00 mL) was added lithium hydroxide (0.05 g, 1.99 mmol). The mixture was stirred at rt for 18 h and then concentrated under reduced pressure. The residue was taken up in water and washed with ether. The aqueous layer was acidified to pH 3.5 and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate and concentrated to give the title compound (0.092 g, 100%). 1H NMR (300 MHz, CD3OD) δ 8.20-8.17 (m, 2H), 8.03-8.01 (m, 1H), 7.18-6.78 (m, 6H), 6.33-6.30 (m, 1H), 4.74 (s, 2H), 4.11 (t, 2H), 3.94 (t, 2H), 3.83 (s, 3H), 3.36-3.34 (m, 3H), 2.26-2.20 (m, 2H). LC/MS m/z 465.2 (M+H)+, RT 2.51 min.
