Versuchsvorschrift

A solution of the (6-{4-[(1R,2S)-2-(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)cyclopropyl]piperidin-1-yl}pyridin-3-yl)methanol (0.3 g, 0.768 mmol) in THF (1.920 ml) was cooled at ice-bath temperature. A solution of NaHMDS (0.922 ml, 0.922 mmol) was added followed by addition of methyl iodide (0.067 ml, 1.075 mmol). The bath was removed and the resulting mixture stirred at room temperature for 2 hours. The mixture was diluted with 1N NaOH (50 ml), extracted with EtOAc (3×30 ml), the organic fractions combined, washed with brine, dried over sodium sulfate, filtered and the volatiles removed in vacuo. The residue was purified by column chromatography on silica gel, Biotage 25 g, using a gradient eluant of 0-30% EtOAc/hexanes to afford the title compound. LC/MS (m/z): 405 (M+H)+.
