Following a procedure analogous to that for the synthesis of Intermediate 1E, N,N-dibutyl-4-chloro-5-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)-1H-pyrazole-3-carboxamide (407 mg, 1.06 mmol) and ethyl 4-fluoro-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate (380 mg, 1.16 mmol) were converted to the title compound (219 mg, 30%). 1H NMR (CD3OD, mixture of amide rotamers) δ 8.26 (td, J=8.4, 1.8 Hz, 1H), 8.19-8.10 (m, 1H), 7.98 (d, J=8.1 Hz, 1H), 7.29-7.07 (m, 3.5H), 6.94 (d, J=7.5 Hz, 0.5H), 4.71-4.48 (m, 2H), 4.47-4.39 (m, 2H), 4.16-3.86 (m, 1H), 3.80-3.37 (m, 5H), 3.26-2.58 (m, 5H), 1.87-0.74 (m, 22H), 0.72-0.66 (m, 1H); MS(ESI+) m/z 609.3 (M+H-THP)+.
