XV 2-(4'-p-Chlorobenzyl-piperazino)-5-oxo-8-ethyl-5,8-dihydro-pyrido(2,3-d)pyrimidine-6-carboxylic acid. SPC22
EXAMPLE XV 2-(4'-p-Chlorobenzyl-piperazino)-5-oxo-8-ethyl-5,8-dihydro-pyrido(2,3-d)pyrimidine-6-carboxylic acid. SPC22 Condensation of 1-p-chlorobenzyl-piperazine with 2-chloro-5-oxo-6-carbethoxy-8-ethyl-5,8-dihydro-pyrido-(2,3-d)pyrimidine, as described in Example VII, gives, in a yield of 74%, 2-(4'-p-chlorobenzyl-piperazino)-5-oxo-6-carbethoxy-8-ethyl-5,8-dihydro-pyrido(2,3-d)pyrimidine; melting point 150°C, after recrystallisation from ethyl acetate. Analysis for C23 H26 ClN5 O3 (molecular weight 455.5): Calculated %: C, 60.59; H, 5.70; N, 15.36; Cl, 7.79. Found %: C, 60.29; H, 5.72; N, 15.38; Cl, 7.76.
