93.02% | for 8 h; Reflux; Large scale | A solution of the above-prepared 3-amino-3-phenylpropanol (1.5 kg)Was dissolved in 1.6 kg (88percent, 30 mol) of formic acid,Add 2.8kg (37percent, 35mo 1) formaldehyde solution, heated to reflux, the reaction 8h.The reaction was quenched, concentrated under reduced pressure, 2L7K was added, adjusted to pH 12 with 10percent aqueous sodium hydroxide solution, and extracted with 3L / 4 times ethyl acetate. Combined with ethyl acetateThe layers were washed twice with 6 L saturated brine. Dried and concentrated under reduced pressure to give 1.65 kg of (s) -3-dimethylamino-3-phenylpropanol, purity (HPLC): 97.36percent yield 93.02percent. Ethyl acetate recovery cycle. |
80% | With sodium cyanoborohydride; acetic acid In acetonitrile at 20℃; for 2 h; | To a solution of (XIII) (0.12 g, 0.807 mmol) in acetonitrile was added, 30percent aq formaldehyde solution (0.325 mL) followed by sodium cyanoborohydride (0.081 g, 1.29 mmol) and it was allowed to stir at room temperature. A few drops of glacial acetic acid were added to maintain the pH near neutrality. The solution was stirred at room temperature for 2 h. After completion of the reaction (TLC), the reaction mixture was concentrated in vacuo. To the residue was added 2 N aq KOH (10 mL). It was then extracted with ethyl acetate (3x10 mL). The ethyl acetate layer was then washed with 1 N HCl (3x5 mL). The combined HCl extracts were basified with solid KOH and then extracted with ethyl acetate (3x10 mL). Combined organic extracts were washed with brine (10 mL), dried over anhydrous Na2SO4, and concentrated in vacuo to afford crude product, which was purified by column chromatography (40percent EtOAc/MeOH) to furnish 15 (0.115 g, 80percent) as a hygroscopic solid. |
