---|---|---|
83.5% | With sodium carbonate; zinc dibromide; In water; at 200℃; for 3h;Autoclave; | In 1L three-necked flask were successively added water 800ml, sodium carbonate 56g, stir, added in portions D-(-)-α-hydroxyphenylglycine 83.6g, stirring until completely dissolved, transferred in its entirety to a 2L autoclave within , was added 4-ethyl-2,3-bis-oxo-piperazine-1-carbonyl chloride 105g, zinc bromide, 0.7g, stir lid was closed and open stirring, the system was heated to 150 deg.] C, the reaction was continued 3h, stop stirring, cooling, opening the purge valve, decreased to atmospheric pressure, the solution was transferred to a 2L flask, concentrated out most of the methanol, the mother liquor plus active carbon, filtered and the filtrate was placed in an ice-water bath cooled solution of 6mol / L hydrochloric acid PH = 1.5, a lot of white precipitate crystallization, filtration, drying HO-EPCP pure 136.4g, a yield of 81.4%. Purity by HPLC 99.3%. Was prepared as in Example 1 except that: the condensation reaction temperature is 200 deg.] C, the condensation reaction time was 3h. The resulting HO-EPCP pure 140.1.9g, a yield of 83.5%. Purity by HPLC 97.9%. |
