| Abstract: | R - （ ＋ ） - lansoprazole was synthesized from 2 - Chloromethyl - 3 - methyl - 4 - （2,2,2 - trifluoroethoxy） pyri - dine hydrochloride by condensation and asymmetric oxidation. By purifying, chemical purity of the product was 99.6% , optical purity was 99.8% , and with an overall yield of 37.9%. This synthetic process was under mild reactive conditions and with cheaper raw material. The process was suitable for industrial producing. The structure of R - （ ＋ ） lansop - razole was confirmed by MS, ^1H - NMR, ^13 C - NMRand IR. |
