A bulk enabling synthesis of the CCR-5 receptor antagonist, Maraviroc (UK-427,857) (1), is presented. Synthesis of the three key fragments, β-amino ester 3, 4,4-difluorohexanecarboxylic acid (2), and 1,3,4-triazole-substituted tropane fragment 4 are described. Coupling strategies for these fragments are discussed and described, including synthetic challenges, protection strategies, impurity generation
