Reaction Steps

To a solution of ethyl ((1S)-5-{3-[[5-(4,5-dimethyl-1,3-thiazol-2-yl)-2-pyridinyl]propyl)amino]-propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (Example 267) (70 mg, 0.15 mmol) in a mixture of THF (2 mL), methanol (2 mL), and water (1 mL) was added LiOH (40 mg, 1.74 mmol). The mixture was stirred at rt for 18 h and then concentrated under reduced pressure. The residue was taken up in water and acidified using H3PO4 (5% solution in water). The aqueous phase was extracted with ethyl acetate, and the combined organic layers were dried (Na2SO4), filtered, and concentrated under reduced pressure to provide the product (56 mg, 86%). 1H NMR (400 MHz, DMSO-d6) δ 8.44 (d, 1H), 7.80 (d, 1H), 7.06 (d, 1H), 6.79 (d, 1H), 6.71 (dd, 1H), 6.56 (d, 1H), 3.95 (t, 2H), 3.62 (t, 2H), 3.44-3.25 (m, 3H), 2.81-2.62 (m, 3H), 2.30-2.23 (m, 8H), 1.99-1.96 (m, 2H), 1.65-1.53 (m, 3H), 0.87 (t, 3H); LC-MS: RT=2.73 min, (M+H)+ 480.2.
