2-Piperidinecarboxylic acid, 5-[(phenylmethoxy)amino]-, phenylmethyl ester, (2S,5R)-, ethanedioate (1:1) Use and Manufacturing
To stir, Thermometer in a 2000 ml four-necked flask500 grams of ethyl acetate, 135.0 g (0.4 mole) of benzyl 5-benzyloxyiminopiperidine-2S-carboxylate (III3) are added, Maintaining negative 20°C to negative 15°C, 201.0 grams of concentrated sulfuric acid (2.0 moles) was added dropwise.After dripping, stir for 1 hour.At negative 20°C, Add 190.0 g (0.9 moles) of sodium triacetoxyborohydride, The reaction was stirred at -20°C to -15°C for 5 hours.Keep the temperature below 0°C, Add 200 grams of water to quench the reaction;Ammonia is neutralized until the system has a pH of 7-8.The layers were separated and the organic layer was washed twice with 100 g each of saturated saline.The organic phase is concentrated to recover the solvent, Then, 320 g of ethyl acetate and 160 g of methanol were added to the resulting residue.52.0 g (0.42 mol) of oxalic acid dihydrate, After heating to 45°C and stirring for 2 hours, Cool, filter.The cake was washed with 100 g of a mixture of ethyl acetate/methanol (2:1) and washed with 50 g of ethyl acetate.All filtrates were combined for Example 6.The filter cake was dried under vacuum to obtain 118.8 g of the single isomer 5R-benzyloxy aminopiperidine-2S-carboxylic acid benzyl oxalate, the chiral HPLC purity was 99.7percent, and the yield was 69.0percent.The benzyl (2S)-5-((benzyloxy)amino)piperidine-2-carboxylate solution (50 mL) as obtained in the previous step was heated to 45 °C, 40°C methanol (20 mL) and oxalic aicd (2.4 g, 26.7 mmol) in methanol (5 mL) solution were added, and the system was cooled to 0°C, still stood for 6 h, filtrated, and the filter cake was washed with ethyl acetate (20 mL), added to methanol (25 mL), heated to 80°C, dissolved completely, cooled to 25 °C, still stood for 2h, filtered, and the filter cake was washed with methanol (5 mL), dried to obtain the title compound in white color (4.3 g, yield 37.7 percent).Example 10
