Versuchsvorschrift

To a stirred solution of 1-isopropyl-1H-indazole-3-carboxylic acid (126 mg, 0.619 mmol), tert-butyl cis-5-amino-2-[(4-hydroxytetrahydro-2H-pyran-4-yl)methyl]piperidine-1-carboxylate (234 mg, 0.743 mmol, step 5 of Example 2), N,N-diisopropylethylamine (96 mg, 0.743 mmol) in N,N-dimethylformamide (3 mL) was added diethyl cyanophosphonate (121 mg, 0.743 mmol) at room temperature, and the mixture was stirred at the same temperature for 18 h. The mixture was concentrated under reduced pressure and the resulting residue was chromatographed on a column of silica gel eluting with n-hexane/ethyl acetate (1:1) to give 292 mg (94%) of the title compound as a colorless oil.
