Following a procedure analogous to that for the synthesis of Intermediate 93B, 2-(4-chloro-3-(dibutylcarbamoyl)-5-methyl-1H-pyrazol-1-yl)-5-(naphthalen-2-ylsulfonylcarbamoyl)benzoic acid (Intermediate 91F, 32 mg, 0.051 mmol) and 1-methyl-1,2,3,4-tetrahydroisoquinoline (Parkway Scientific, 8 mg, 0.056 mmol) were converted to the title compound (12 mg, 31%) following purification by preparative HPLC. 1H NMR (DMSO-d6, mixture of amide rotamers) δ 8.65 (s, 1H), 8.21 (d, J=8.1 Hz, 2H), 8.16-8.03 (m, 4H), 8.01-7.94 (m, 1.5H), 7.91 (br s, 0.5H), 7.77-7.61 (m, 3H), 7.27-6.93 (m, 2H), 5.48-5.31 (m, 0.5H), 3.68-3.55 (m, 1H), 3.17-2.57 (m, 4.5H), 2.55 (t, J=5.5 Hz, 3H), 2.20 (s, 3H), 1.53-1.36 (3.5H), 1.29-1.23 (m, 2.5H), 1.21-1.12 (m, 4H), 0.95-0.82 (m, 3.5H), 0.66 (d, J=7.3 Hz, 3H), 0.56 (br s, 0.5H); MS(ESI+) m/z 754.3 (M+H)+.
