Abstract: | Bepotastine besilate was synthesized from (4-chlorophenyl)-(pyridine-2-yl)-methanone by asymmetric hydrogenation with (S)-Ru(BINAP)Cl2]2(NEt3) as the catalyst to give (S)-(+)-(4-chlorophenyl)-(pyridine-2-yl)-methanol, which was subjected to condensation with ethyl 4-(4-bromopiperidin-1-yl)butyrate followed by hydrolysis and salification with an overall yield of 57%. |
