Procedure

To a solution of ethyl ((1S)-5-{3-[[2-(4-ethylphenyl)-5-methyl-4-pyrimidinyl](methyl)amino]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (Example 343,140 mg, 0.290 mmol) in a mixture of THF (5 mL), water (5 mL), and EtOH (2.5 mL) was added LiOH (27.5 mg, 1.15 mmol). After vigorously stirring for 24 h, the reaction mixture was acidified to pH ˜5 using HCl (1 N aqueous solution) and extracted with CH2Cl2. The combined organic layers were dried (Na2SO4), filtered, and then concentrated under reduced pressure to give the product (118 mg, 89%) as a white foam. 1H NMR (400 MHz, acetone-d6) δ 1.26 (t, 3H), 1.70-1.76 (m, 1H), 2.18-2.21 (m, 2H), 2.37 (s, 3H), 2.33-2.42 (m, 2H), 2.67-2.85 (m, 5H), 3.28 (s, 3H), 3.44-3.45 (m, 1H), 3.86 (t, 2H), 4.07 (t, 2H), 6.71 (d, 1H), 6.78 (s, 1H), 7.12 (d, 1H), 7.27 (d, 2H), 8.08 (s, 1H), 8.35 (d, 2H); LC-MS: RT=2.53 min, (M+H)+ 460.4.
