Versuchsvorschrift

Benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate (679 mg, 1.53 mmol) was added to a solution of (2R)-2′-oxo-1,1′,2′,3-tetrahydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridine]-5-carboxylic acid (described in Intermediate 1) (364 mg, 1.30 mmol), (3S,5S,6R)-3-amino-6-methyl-5-phenyl-1-(2,2,2-trifluoroethyl)piperidin-2-one hydrochloride (described in Intermediate 4) (380 mg, 1.18 mmol), and N,N-diisopropylethylamine (2.06 mL, 11.8 mmol) in DMF (6 mL), and the resulting mixture was stirred at 23° C. for 16 h. The reaction mixture was then diluted with water (200 mL), and the precipitate was collected by filtration, washed with water, and air dried. The crude product was purified by flash column chromatography on silica gel, eluting with hexanes initially, grading to 100% EtOAc to afford the title compound. HRMS: m/z=549.2123, calculated m/z=549.2108 for C30H28F3N4O3. 1H NMR (500 MHz, CDCl3) δ 8.74 (s, 1H), 8.14 (dd, 1H, J=5.3, 1.5 Hz), 7.76 (s, 1H), 7.73 (d, 1H, J=7.8 Hz), 7.37-7.33 (m, 3H), 7.28 (t, 1H, J=7.6 Hz), 7.22-7.19 (m, 3H), 7.00 (d, 1H, J=7.4 Hz), 6.82 (dd, 1H, J=7.4, 5.3 Hz), 4.99-4.89 (1H, m), 4.53 (dt, 1H, J=11.6, 5.9 Hz), 3.93 (p, 1H, J=6.0 Hz), 3.69 (dd, 2H, J=16.1, 9.5 Hz), 3.64 (m, 1H), 3.34-3.24 (m, 1H), 3.11 (dd, 2H, J=16.0, 6.5 Hz), 2.81 (m, 1H), 2.56 (q, 1H, J=12.5 Hz), 1.06 (d, 3H, J=6.5 Hz).
