A new large-scalable preparation of TAK-779 (1), a non-peptide CCR5 antagonist, has been developed. The route selection was focused on in the process research. The selective reduction of commercially available benzonitrile derivative (4) as the starting material with sodium bis(2-methoxyethoxy)aluminum hydride followed by the Wittig reaction, hydrogenation, and intramolecular acylation gave benzocycloheptanone (7) in good yield. The conversion of α,α-unsaturated carboxylic acid (8) led from 7 to benzyl alcohol (9) and shortened the number of steps using non-protected 4-aminobenzyl alcohol. The reductive alkylation of Me2NH and tetrahydro-4H-pyran-4-one (12) smoothly gave a tertiary amine (3). The coupling of 2 chlorinated 9, and 3 successfully led to an ammonium chloride (1). A new inexpensive preparation which did not require a chromatographic method was achieved.

The search for new small-molecule CCR5 antagonists by high-throughput screening (HTS) of the Takeda chemical library using [125I]RANTES and CHO/CCR5 cells led to the discovery of lead compounds (A, B) with a quaternary ammonium or phosphonium m
