摘要

The invention concerns a series of novel phenoxyacetic acid ethers (and pharmaceutically acceptable salts thereof) of the formula I in which R1 is H or F, R2 and R3 are H or (1-3C)alkyl, Z is CH2OH or a group -CO.R4 in which R4 is OH, NH2 or (1-6C)alkoxy. The invention also includes pharmaceutical compositions for use in treating obesity and related conditions and provides processes for the manufacture of the novel ethers.
