実験手順

A mixture of 3-fluoro-4-nitrobenzonitrile (55.5 g, 334 mmol), 1-[(2R,3R,7S)-2,3-diphenyl-1,4-dioxaspiro[4.5]dec-7-yl]methanamine (103 g, 318 mmol) and potassium carbonate (88 g, 637 mmol) in acetonitrile (2654 mL) was stirred at RT for 5 days (˜200 mL DCM was added to help with solubility). The resulting solution was filtered and the solids washed with MeCN. The resulting solution was concentrated to give the crude product that was dissolved in MeOH (500 mL) and allowed to crystallize with stirring. The slurry was allowed to stir at RT overnight, filtered and the solids dried under reduced pressure to give 3-({[(2R,3R,7S)-2,3-diphenyl-1,4-dioxaspiro[4.5]dec-7-yl]methyl}amino)-4-nitrobenzonitrile (131.41 g, 88% yield). The product was used without further purification.
