  inhibitory activity. Starting from 2-chloro-N-(S)-phenyl[(2S)-piperidin-2-yl]methyl}-3-(trifluoromethyl)benzamide (2, SSR504734), the introduction of heteroaromatic rings enabled an increase in the GlyT1 inhibitory activity. Subsequent optimization led to the identification of 3-chloro-N-(S)-[3-(1-ethyl-1H-pyrazol-4-yl)phenyl][(2S)-piperidine-2-yl]methyl}- 4-(trifluoromethyl)pyridine-2-carboxamide (7w)
