To a suspension of K2CO3 (132 mg, 0.96 mmol) in DMF (5 mL) was added 3-methoxyphenol (36 mg, 0.290 mmol), followed by the portionwise addition of ethyl ((1S)-5-{3-[(2-chloro-5-methyl-4-pyrimidinyl)(methyl)amino]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate prepared in Example 342. The reaction mixture was stirred at 80° C. for 48 h, and then concentrated under reduced pressure. The residue was purified by silica gel flash chromatography to yield the title compound (56.5 mg, 47%) as a yellow oil. 1H NMR (400 MHz, CDCl3) δ 1.29 (t, 3H), 1.71-1.83 (m, 1H), 2.02 (m, 2H), 2.28 (s, 3H), 2.35-2.47 (m, 2H), 2.75 (dd, 1H), 2.79-2.96 (m, 2H), 3.15 (s, 3H), 3.49-3.57 (m, 1H), 3.56-3.61 (m, 2H), 3.78 (s, 3H), 3.81 (t, 2H), 4.19 (q, 2H), 6.64 (dd, 1H), 6.69-6.78 (m, 3H), 7.05 (d, 1H), 7.21-7.27 (m, 2H), 7.80 (s, 1H); LC-MS: RT=2.85 min, (M+H)+ 506.3.
