| Abstract: | Condensation of substituted diethyl-malonates with phenylamidine hydrochloride gives liguid crystals with a pyrimidine ring, which produces the compound 5-cyano-2-(4'-n-pentyl-4- -pyrimidine in high yield by subsequent group transformation. The compound sythesized has good photo-,thermal and chemical stability, being thus an excellent mesomophic material. |
