Reaction Steps

To a solution of ethanolamine (1.23 g, 20.1 mmol) in anhydrous MeOH (50 mL) at 0° C. was added benzaldehyde (2.13 g, 20.0 mmol) and molecular sieves (10 pieces). The resulting mixture was gradually warmed to room temperature and stirred for 120 h. The reaction mixture was filtered while rinsing with CH2Cl2. The filtrate was evaporated, and the residue was dried under vacuum overnight to afford off-white oily Compound 1 (2.63 g, 87%). The compound was used for the next step without further purification. 1H NMR (CDCl3) δ 2.40 (s, 1H), 3.70 to 3.80 (m, 2H), 3.85 to 4.0 (m, 2H), 7.35 to 7.50 (m, 3H), 7.68 to 7.79 (m, 2H), 8.32 (s, 1H); 8.11 (d, 2H); 13C NMR (CDCl3) δ 62.28, 63.17, 128.1, 128.52, 130.78, 135.72, 163.10.
