Practical synthesis of an orally active CCR5 antagonist, 7-{4-[2-(Butoxy)-ethoxy]phenyl}-N-(4-{[methyl(tetrahydro-2H-pyran-4-yl)amino] methyl}phenyl)-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide

A practical method of synthesizing 7-{4-[2-(butoxy)ethoxy]-phenyl}-N-(4- {[methyl(tetrahydro-2H-pyran-4-yl)amino]methyl}-phenyl)-1-propyl-2, 3-dihydro-1H-1-benzazepine-4-carboxamide (8), an orally active CCR5 antagonist, has been developed. Methyl 7-bromo-1-propyl-2,3-dihydro-1H-1-benzazepine-4- caboxylate (14a) was synthesized in good yield by the esterification of 4-[(4-bromo-2-formylphenyl)(propyl)amino]butanoic acid (13) followed by an intramolecular Claisen type reaction with 28% sodium methoxide in dimethyl carbonate as a solvent in one pot. The Suzuki-Miyaura reaction of 14a and 1-bromo-4-(2-butoxyethoxy)benzene (10) followed by hydrolysis and amidation gave 8. A new inexpensive method without chromatographic purification was established.

BENZAZEPINE DERIVATIVES, PROCESS FOR THE PREPARATION OF THE SAME AND USES THEREOF

Compounds of the general formula (I): or salts thereof, which exhibit CCR5 antagonism and exert preventive and therapeutic effects against HIV infections: wherein R1 is a 5- to 6-membered aromatic ring which bears a substituent represented by the general formula: R-Z1-X-Z2- (wherein R1 is hydrogen or optionally substituted hydrocarbyl; X is optionally substituted alkylene; and Z1 and Z2 are each a heteroatom) and may be further substituted, with R being optionally bonded to the aromatic ring to form another ring; Y is optionally substituted imino; and R2 and R3 are each optionally substituted aliphatic hydrocarbyl or an optionally substituted hetero-alicyclic group.
