摘要

This contribution describes process development leading to the production of 1-(1-pyridin-2- yl methyl-piperidin-4-yl)-1 H-indole (11). The title compound 11 was produced via a Leimgruber-Batcho indole synthesis using key intermediates 2-(2, 2-dimethoxyethyl) benzenamine (6) and, 1-(2-pyridinylmethyl)-4-piperidinone camphor sulfonate (9). Direct crystallization of 11 from IPA or ethanol-water was developed to provide (11) with< 1% ...
