Reaction Conditions

Reaction Steps

To a suspension of 60% sodium hydride (535.0 mg, 13.7 mmol) in N,N-dimethylformamide (2.5 mL) was added methanesulfonamide (1.3 g, 13.8 mmol) at room temperature. The resulting mixture was stirred at 25° C. for 1 h to afford Solution A43. A solution of 2-[3-(1-cyclopropyl-1H-tetrazol-5-yl)-phenyl]-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (544.6 mg, 1.4 mmol) and 1,1′-carbonyldiimidazole (442.0 mg, 2.76 mmol) in N,N-dimethylformamide (2.0 mL) was stirred at 70° C. for 1 h and cooled to room temperature to afford Solution B43. Solution B43 was added to Solution A43 and the resulting mixture was stirred at 25° C. for 1 h. To the reaction mixture was added water (0.5 mL). The mixture was filtered to remove the insoluble solid, and the filtrate was purified by Waters automated flash system (column: Xterra 30 mm×100 mm, sample manager 2767, pump 2525, detector: ZQ mass and UV 2487, solvent system: acetonitrile and 0.1% ammonium hydroxide in water) afforded N-{2-[3-(1-cyclopropyl-1H-tetrazol-5-yl)-phenyl]-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonyl}-methanesulfonamide (195.7 mg, 30%) as a white solid: MS (ESI) M+1=467.2.
