반응 단계

Add dropwise via an addition funnel a solution of [2-(4-Hydroxy-phenyl)-ethyl]-carbamic acid methyl ester (13.0 g, 62.2 mmol) in tetrahydrofuran (100 mL) to a stirred solution at 0° C. of 1.0M lithium aluminum hydride in tetrahydrofuran (156 mL) and tetrahydrofuran (250 mL). Reflux for 18 hours, cool to 0° C., quench with saturated aqueous ammonium chloride then stir at room temperature for 3 hours. Filter off the aluminum salts, concentrate on a rotary evaporator, and dry under vacuum to yield 6.6 g of 4-(2-methylamino-ethyl)-phenol: 1H NMR (DMSO-d6, 300.00 MHz): 6.97 (d, 2H); 6.65 (d, 2H); 2.65-2.55 (m, 4H); 2.28 (s, 3H).
