Compounds are provided that act as potent antagonists of the CCR1 receptor, and which
have been further confirmed in animal testing for inflammation, one of the hallmark
disease states for CCR1. The compounds are generally aryl piperazine derivatives
and are useful in pharmaceutical compositions, methods for the treatment of
CCR1-mediated diseases, and as controls in assays for the identification of
competitive CCR1 antagonists.

with pyrazoles provided a series of unexpected N,O-aminal derivatives, through a 1,4-conjugated addition at the β-carbon of the 5-bromo enones instead of the expected nucleophilic substitution of the bromine. This reaction also furnished the 1,3-regioisomer of the pyrazole. A similar reaction of pyrazoles using 5-bromo enaminones furnished only N-alkylated pyrazoles—with high regioselectivity and at
