Reaction Steps

Following a procedure analogous to that for the synthesis of Intermediate 122G, 4-chloro-5-methyl-1-(4-(naphthalen-2-ylsulfonylcarbamoyl)-2-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)phenyl)-1H-pyrazole-3-carboxylic acid (Intermediate 122F, 50 mg, 0.079 mmol) and N-butyl-3,4-dichloroaniline (Aldrich, 10 mg, 0.046 mmol) were converted to the title compound. 1H NMR (1:1 CD3OD:CDCl3, mixture of amide rotamers) δ 8.73 (s, 1H), 8.12-8.00 (m, 4H), 7.97-7.94 (m, 1H), 7.74-7.66 (m, 2H), 7.57 (br s, 1H), 7.46 (br s, 1H), 7.36 (br s, 1H), 7.26-7.19 (m, 4.5H), 7.12-7.10 (m, 0.5H), 7.00 (br s, 1H), 6.73 (br s, 1H), 6.66 (br s, 0.5H), 6.50 (br s, 0.5H), 4.66 (br s, 0.5H), 4.51 (br s, 0.5H), 4.39 (br s, 0.5H), 4.25 (br s, 0.5H), 3.85 (br s, 2H), 3.58 (br s, 2H), 3.13 (br s, 1H), 2.81 (br s, 1H), 2.20-2.16 (m, 3H), 1.38-1.21 (m, 4H), 0.93-0.83 (m, 3H); MS(ESI+) m/z 760.2 (M+H)+.
