标 题 :Method for producing intermediate useful for synthesis of SGLT inhibitor
发明人：LI QING RI; YOON HEE KYOON
权利人:DAEWOONG PHARMACEUTICAL CO LTD
摘要:A method of preparing an intermediate useful for the synthesis of a diphenylmethane derivative that can be used as an SGLT inhibitor is described. A method of synthesizing a compound of Formula 7 can address problems of existing synthesis processes requiring the synthesis of the Grignard reagent and management of related substances. In addition, the method can minimize the generation of related substances, and thus does not require reprocessing of reaction products, thereby simplifying the process. Accordingly, the production yield of a diphenylmethane derivative can be maximized.

标题:Synthesis of C-alkyl-triethylenediamines
发明人：NIEH EDWARD C Y
权利人:TEXACO DEVELOPMENT CORP
摘要:A liquid phase synthesis of C-alkyl-triethylenediamines involves heating to elevated temperatures of from about 200° C to 300° C a suitable N-(2-hydroxyalkyl) piperazine feedstock in the presence of a catalytic amount of a pentavalent acidic phosphorus compound and then recovering the C-alkyl-triethylenediamine product from the resulting reaction product mixture.

标 题:3-substituted pyridine compounds and related synthesis
发明人：HOGLEN DEAN KENT
权利人:NOVARTIS AG; NOVARTIS ERFIND VERWALT GMBH; HOGLEN DEAN KENT
摘要:The present invention relates to 3-substituted and 2,3-disubstituted pyridine compounds of formula (I), wherein R1 is C1-C4 haloalkyl and R4 is H, halogen or C1-C4 alkylthio; and acid addition salts thereof which are useful as intermediates in the synthesis of pyridylsulfonylurea herbicides. The invention also relates to arylation of alcohols using a pyridinediazonium salt. More particularly the arylation process of the instant invention relates to the synthesis of 2,3-disubstituted pyridine compounds via anhydrous diazotization of 3-aminopyridines to form a diazonium salt intermediate that is then reacted with the appropriate alcohol to produce the desired product. The invention additionally relates to pyridine-3-diazonium salt intermediates.
