Procedure
A stirred solution of 2-(7-methyl-1H-indazol-5-yl)-1-(1-neopentyl-1H-tetrazol-5-yl)ethanamine (20.0 mg, 0.06 mmol) in dimethylformamide (1.0 mL) at 0° C. was treated with carbonyl diimidazole (11.0 mg, 1.1 equiv). The reaction was stirred for 5 min at 0° C., warmed to room temperature, stirred for 10 min, and treated with 3-(piperidin-4-yl)-3,4-dihydroquinazolin-2(1H)-one (15.0 mg, 1.1 equiv). The mixture was stirred at room temperature overnight. The solvent was evaporated and the residue purified by column chromatography to afford 22.0 mg (64%). 1H-NMR (CD3OD, 500 MHz) δ 0.90 (s, 9H), 1.35-1.60 (m, 4H), 2.53 (s, 3H), 2.71-2.85 (m, 2H), 3.41-3.52 (m, 2H), 3.98-4.14 (m, 5H), 4.24 (d, J=14.3, 1H), 4.34 (m, 1H), 6.77 (d, J=7.9, 1H), 6.94 (dd, J=7.6, 7.3, 1H), 7.06-7.17 (m, 3H), 7.45 (s, 1H), 7.88 (s, 1H), 7.98 (s, 1H). Mass spec.: 571.28 (MH)+.
