Reaction Steps
Following the same procedure in Example 1, Step A, using 2-tert-butyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-benzimidazole-5-sulfonyl chloride (61 mg, 0.17 mmol), piperidine (0.2 mL, 2.0 mmol) and DMAP (50 mg, 0.41 mmol) in MeCN (5 mL). The crude product was purified by MPLC using Hex/EtOAc (1:1) on silica gel to give 31 mg (45%) of a white solid as the title compound. 1H NMR (400 MHz, METHANOL-D4) δ 1.40 (m, 2 H), 1.47-1.64 (m, 8 H), 1.65 (s, 9 H), 2.25-2.48 (m, 1 H), 2.92-3.05 (m, 4 H), 3.29-3.39 (m, 2 H), 3.88-3.98 (m, 2 H), 4.50 (d, J=7.62 Hz, 2 H), 7.82 (dd, J=8.69, 1.66 Hz, 1 H), 8.01 (d, J=8.79 Hz, 1 H), 8.06 (d, J=1.56 Hz, 1 H); MS (ESI) (M+H)+=420.0; Anal. Calcd for C22H33N3O3S+1.10 TFA+0.50H2O+0.10 CH3OH (557.23): C, 52.38; H, 6.42; N, 7.54. Found: C, 52.38; H, 6.43; N, 7.58.
