Reaction Steps

A mixture of (7R)-7-amino-4-chloro-9-(2,2,2-trifluoroethyl)-6,7,9,10-tetrahydroazepino[3,4-e]indazol-8(3H)-one bis-methanesulfonate (16 mg, 0.030 mmol, described in Example 7, Step B), (±)-2′-oxo-1′,2′,5,7-tetrahydrospiro[cyclopenta[c]pyridine-6,3′-pyrrolo[2,3-b]pyridine]-3-carboxylic acid (8.6 mg, 0.030 mmol, described in Intermediate 5), N,N-diisopropylethylamine (20 mg, 27 uL, 0.15 mmol), HOBT (5.6 mg, 0.037 mmol), and EDC (7.0 mg, 0.037 mmol) in DMF (0.5 mL) was stirred at ambient temperature for 18 h. The reaction mixture was purified directly by HPLC using a reversed phase C18 column and eluting with a gradient of H2O:CH3CN:CF3CO2H-90:10:0.1 to 5:95:0.1. The pure, product-containing fractions were concentrated in vacuo to provide the title compound. MS: m/z=596.
