We present an easy and straightforward synthesis of 3-arylpiperidines by Grignard addition of piperidin-3-one with different arylmagnesium bromide reagents and acidic dehydroxylation of the resulting tertiary alcohol with the combination of triethylsilane and boron trifluoride etherate. This facile strategy was further used to synthesize preclamol. A highly regioselective dehydration of 3-arylpiperidin-3-ol
