A pyrimidine derivative of formula (I):
wherein: R1 is an optional substituent as defined within; Rx is selected from halo, hydroxy, nitro, amino, cyano, mercapto, carboxy, sulphamoyl, formamido, ureido or carbamoyl or a group of formula (Ib): A—B—C— as defined within; Q1 and Q2 are independently selected from aryl, a 5- or 6-membered monocyclic moiety; and a 9- or 10-membered bicyclic heterocyclic moiety; and one or both of Q1 and Q2 bears on any available carbon atom one substituent of formula (Ia) as defined within; and Q1 and Q2 are optionally further substituted; or a pharmaceutically acceptable salt or in vivo hydrolysable ester thereof; are useful as anti-cancer agents; and processes for their manufacture and pharmaceutical compositions containing them are described.

A novel acid-catalysed nucleophilic displacement reaction of pyrimidines is described, involving quinone–methide type chemistry. A wide range of nucleophiles can be tolerated. A similar mechanism is also applied to the synthesis of a tricyclic system.
