Za. Hozien et al., SYNTHESIS AND APPLICATION OF SOME - NEW THIENOPYRIMIDINE DERIVATIVES AS ANTIMICROBIAL AGENTS, Synthetic communications, 26(20), 1996, pp. 3733-3755
The paper describes the synthesis of new ring system 5-phenylthieno[2,
3-d]pyrimidine-4(3H)one (2) Chlorination of (2) with PCl5, POCl3 gave
tile corresponding 4-chloro derivative (4). Several derivatives of the
latter compound have been synthesised and tested for antimicrobial ac
tivity.
