摘 要:為定量控制降糖藥達格列凈中的雜質(zhì),對達格列凈中的2個(gè)雜質(zhì)5-溴-2-氯-2′-乙氧基二苯甲酮(1)和5-溴-2-氯-2′-乙氧基二苯甲烷(2)進(jìn)行了定向合成,以5-溴-2-氯苯甲酸和苯酚經(jīng)縮合、Fries重排,然后乙基化得到雜質(zhì)1,雜質(zhì)1 再經(jīng)還原得到雜質(zhì)2。其結構經(jīng)核磁共振氫譜和質(zhì)譜確證結構。 |
關(guān)鍵詞:達格列凈;雜質(zhì);合成 |

Abstract:To perform the quality control of dapagliflozin, two impurities of dapagliflozin including 5-bromo-2-chlorophenyl-2′-ethoxyldiphenylmethanone(1) and 5-bromo-2-chloro-2′-ethoxyl diphenylmethane(2) were synthesized. Impurity 1 was prepared via condensation, Fries rearrangement and ethylation using 5-bromo-2-chlorobenzoic acid and phenol as the starting materials. Impurity 2 was obtained from reduction of impurity 1. The structures of Impurity 1 and Impurity 2 were characterized using 1H NMR and MS. |
Key words:dapagliflozin; impurity; synthesis |
