Abstract

In a process for cmpds. (I) (where R1 is alkyl opt. halo substd. Ph opt. substd. by halogen or alkyl or RO; R is either 1-12C alkyl opt. interuppted by O or substd. by COOR' (R' being alkyl) a 3-12C alkenyl; R2 is alkyl X,Y or Z' are F, Cl, Br, or I alkyl a NO2; a Z may also be acetyl or S(O)nR", n is 0 1 or 2 and R" is alkyl) by transesterification of (II) with R2OH (III). a weak base is used as catalyst.
