Popis: As part of an effort to develop an industrial synthesis of the LTD4 antagonist RG 12525 (1), several approaches to the intermediate (2-quinolinylmethoxy)phenol 3 were investigated that avoided the generation of the lachrymatory sensitizer α-chloro-2-methylquinoline 2. Utilization of a cyclic sulfate in place of α,α′-dichloro-o-xylene 4 showed promise as a selective dialkylating agent in the conversion of 3 to RG 12525 (1).
