実験手順: Add p-toluenesulfonyl-chloride (0.71 g, 3.71 mmol), portionwise, to a mixture of (3-fluoro-benzyl)-(2-hydroxy-ethyl)-carbamic acid dimethyl-ethyl ester (1 g, 3.71 mmol, prepared from 2-(3-fluoro-benzylamino)-ethanol by methods as are known in the art), triethylamine (0.751 g, 7.4 mmol) and dichloromethane (6 mL). Stir the resulting suspension vigorously overnight at room temperature. Add water (10 mL), separate the organic layer, and extract the aqueous layer with dichloromethane (5 mL), twice. Combine the organic layers and wash with citric acid (5 mL, 20% in water), dry with sodium sulfate and evaporate the solvent to give the final, desired compound. The final compound may be purified by chromatography. Add water (10 mL), separate the organic layer extract the aqueous layer with dichloromethane (5 mL) wash with citric acid (5 mL, 20% in water) dry with sodium sulfate evaporate the solvent

実験手順: Combine 3-fluorobenzylamine (31.1 g, 0.248 mol), 2-chloroethanol (10 g, 0.124 mol) and water (30 g, 1.66 mol) and heat on a steam-bath for ˜5 hours. Add sodium hydroxide (15 g, 0.373 mol) to the cooled solution and heat the resulting mixture on a steam-bath for ˜30 minutes. Add water (˜50 mL) to dissolve the inorganic salts and extract the two-phase mixture twice with 25 mL and 13 mL portions of benzene. Combine the extracts and remove the water by co-distillation with benzene through a modified Claisen flask. The final desired compound may be purified with further distillation. extract the two-phase mixture twice with 25 mL and 13 mL portions of benzene remove the water by co-distillation with benzene through a modified Claisen flask The final desired compound may be purified with further distillation
