: Disclosed herein is an improved process for the preparation of Ivabradine and pharmaceutically acceptable salts thereof. The invention more particularly disclosesthe synthesis of key intermediates viz.,(S)-N-[(4,5-dimethoxybenzocydobut-l-yl)-methyl]-N- (methyl)amine hydrochloride of Formula-II and 3-(3-Iodopropyl)-7,8-dimethoxy-1,3-dihydro-2H-3-benzapin-2-one of Formula-III, and its use in industrial synthesis of Ivabradine and pharmaceutically acceptable salts thereof.

The invention provides a preparation method of (1S)-4,5-dimethoxy-1-[(methylamino)methyl]benzocyclobutane hydrochloride, which specially comprises the following step: carrying out reduction and salting-out on 4,5-dimethoxybenzocyclobutyl-1-methyl formamide in an inert solvent to finally obtain the (1S)-4,5-dimethoxy-1-[(methylamino)methyl]benzocyclobutane hydrochloride (I). The reaction is simple to operate, has the advantages of mild reaction conditions, clean and accessible raw/auxiliary materials, low overall cost, high chemical and enantiomer purity and the like, and therefore, is suitable for industrial production.

Several chemoenzymatic routes have been evaluated for the production of the heart-rate reducing agent ivabradine. Lipases and ω-transaminases have been identified as useful biocatalysts for the preparation of key enantiopure precursors. The lipase-catalysed kinetic resolution by alkoxycarbonylation of a racemic primary amine and subsequent chemical reduction of the resulting carbamate provided an N-methylated (S)-amine, one step away from ivabradine. Alternatively, the dynamic kinetic resolution by asymmetric bioamination of an aldehyde precursor enabled, in a four-step sequence, the preparative scale synthesis of enantiopure ivabradine in 50% overall yield.
