実験手順
To a solution of 4-(5-chloro-3-methyl-2-pyridin-3-yl-indol-1-ylmethyl)-benzonitrile (Example 17, 179 mg, 0.5 mmol) in DMF (5 mL) is added sodium azide (97 mg, 1.5 mmol) and ammonium chloride (80 mg, 1.5 mmol) and the mixture is heated to 120° C. The reaction mixture is cooled to room temperature and filtered. The filtrate is purified by reverse phase HPLC with Xbridge C18 and a gradient of 0.1% NH4OH in acetonitrile to give 5-chloro-3-methyl-2-pyridin-3-yl-1-[4-(2H-tetrazol-5-yl)-benzyl]-1H-indole. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.21 (s, 3H), 5.34 (s, 2H), 6.81 (d, J=8.1 Hz, 2H), 7.11 (br. s, 1H), 7.17 (dd, J=8.7, 2.1 Hz, 1H), 7.48-7.53 (m, 2H), 7.67 (d, J=2.0 Hz, 1H), 7.77 (d, J=8.3 Hz, 2H), 7.80-7.84 (m, 1H), 8.60 (d, J=1.5 Hz, 1H), 8.62 (dd, J=4.8, 1.5 Hz, 1H). HRMS (ESI) m/z 401.1276 [(M+H)+ Calcd for C22H18N6Cl: 401.1281].
