Abstract
Oppfinnelsen angår en fremgangsmåte for fremstilling av en forbindelse med formel (I): hvori R9 er valgt fra: C1-8 alkyl, C3-8 cykloalkyl, (CH2)nPh og (CH2)n heteroaryl hvori n = 0, 1 eller 2, hvor hver gruppe eventuelt kan være substituert på et hvilket som helst karbonatom med en eller flere grupper valgt uavhengig fra: halogen, hydroksy, cyano, nitro, C1-4 alkoksy, C1-4 haloalkoksy, C1-4 alkanoyl, C1-4 haloalkanoyl, C1-4 alkylsulfinyl, C1-4 haloalkylsulfinyl, C1-4 alkylsulfonyl, C1-4 haloalkylsulfonyl, C3-8 cykloalkyl og C3-8 halocykloalkyl; og R9 kan være hydrogen; hvilken fremgangsmåte innbefatter reaksjon mellom et cyanoacetat med formel (II): hvori R9 er som definert ovenfor, med formaldehydcyanohydrin og en uorganisk base i et polart løsemiddel ved en temperatur ikke overskridende 20°C.
