Procedure

A solution of N-[2-[4-[[4-(2-oxazolyl)phenyl]methyl]phenoxy]ethyl]-4-morpholineethanamine (0.25 g, 0.6 mmol) and methyl 4-formylbenzoate (0.11 g, 0.66 mmol) in dichloroethane (5 mL) was stirred as sodium triacetoxyborohydride (0.16 g, 0.74 mmol) was added and stirred for 17 h. The reaction was diluted with water and extracted with ethyl acetate. The combined organic extracts were dried and concentrated. Purification by chromatography on silica gel using a gradient of methanol in dichloromethane gave 0.28 g of methyl 4-[[[2-(4-morpholinyl)ethyl][2-[4-[[4-(2-oxazolyl)phenyl]methyl]phenoxy]ethyl]amino]-methyl]benzoate; 1H NMR (400 MHz, CDCl3) δ 7.97 (m, 4H), 7.68 (s, 1H), 7.42 (d, 2H), 7.27 (d, 2H), 7.21 (s, 1H), 7.08 (d, 2H), 6.78 (d, 2H), 4.03 (t, 2H), 3.96 (s, 2H), 3.92 (s, 3H), 3.79 (s, 2H), 3.66 (m, 4H), 2.92 (t, 2H), 2.73 (t, 2H), 2.47 (m, 2H), 2.42 (m, 4H) ppm.
