An improved chemical synthesis for intermediates of compounds having useful biological activity is disclosed, where the use of PBr3 is employed as a reagent for a selective ring opening of cyclopropylcarbinols to give bromopropylidene products which are highly selectively the E isomer.
The invention provides compounds having the formula:
wherein R
1
is halogen. The invention also provides compositions comprising the compounds, and methods of treating diseases or disorders that comprise administering one or more of the compounds to a subject in need thereof. The disclosed compounds have CCR1 antagonist activity.
