Procedure

To a suspension of 60% sodium hydride (267.5 mg, 6.9 mmol) in N,N-dimethylformamide (2.5 mL) was added cyclopropanesulfonamide (0.83 g, 6.9 mmol) at room temperature. The resulting mixture was stirred at 25° C. for 1 h to afford Solution A42. A solution of 4,4-dimethyl-2-[3-(1-methyl-1H-tetrazol-5-yl)-phenyl]-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (254.1 mg, 0.7 mmol) and 1,1′-carbonyldiimidazole (221.0 mg, 1.4 mmol) in N,N-dimethylformamide (2.0 mL) was stirred at 70° C. for 1 h and cooled to room temperature to afford Solution B42. Solution B42 was added to Solution A42 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 cyclopropanesulfonic acid {4,4-dimethyl-2-[3-(1-methyl-1H-tetrazol-5-yl)-phenyl]-1,2,3,4-tetrahydro-quinoline-6-carbonyl}-amide (97.8 mg, 30%) as a white solid: MS (ESI) M+1=467.1.
