Reaction Steps

To 50 mg (0.1 mmol) of 8-[4-[(cis)-4-(5-cyano-1-methyl-1H-indole-3-yl)cyclohexyl]-1-piperazinyl]-6-quinolinecarboxylic acid in 1 mL of MeOH and 3 mL of C6H5CH3 at 23° C. was added 0.9 mL (0.39 mmol) of a 10% solution of (CH2)3SiCHN2 in hexanes. After stirring at 23° C. for 12 hours, the volatiles were removed by rotary evaporation. The crude product was chromatographed on silica gel eluting with 20:1 CH2Cl2:MeOH. The product fractions were pooled, stripped, and treated with 5 mg (0.05 mmol) of (CO2H)2 in absolute EtOH to give 20 mg (0.04 mmol, a 40% yield) of the oxalate salt of the title compound as a tan crystalline solid. mp: 153-155° C.; MS (ES) m/z: 599 (MH)+.
