Reaction Steps

To a solution of [(1S-5-(3-bromopropoxy)-2,3-dihydro-1H-inden-1-yl]acetate (Example 45) (93.4mg, 0.274 mmol) and 4-(4-ethyl-1,3-oxazol-2-yl)-2-methoxyphenol (40.0 mg, 0.182 mmol) (Example 172) in DMF (4 mL) was added Cs2CO3 (118.9 mg, 0.365 mmol) and water (4 drops). The reaction mixture was stirred at rt for 16 h, then filtered, and the filtrate concentrated under reduced pressure. Purification by preparative HPLC (acetonitrile/water (v/v)=1:1 to 9:1 gradient) gave 73.6 mg (84%) of the title compound as an off-white solid. 1H NMR (400 MHz, CD2Cl2) δ 7.57 (d, 2H), 7.41 (s, 1H), 7.05 (d, 1H), 6.98 (d, 1H), 6.80 (s, 1H), 6.72 (d, 1H), 4.25 (t, 2H), 4.17 (m, 4H), 3.93 (s, 3H), 3.51 (m, 1H), 2.85 (m, 2H), 2.71 (dd, 1H), 2.62 (q, 2H), 2.40 (m, 2H), 2.31 (t, 2H), 1.76 (m, 1H), 1.29 (m, 6H).
