To a solution of 2-phenyl-2H-tetrazole-5-carboxylic acid (0.10 g, 0.53 mmol, 1 eq) and (S)-1-(imidazo[1,2-a]pyrazin-8-yl)pyrrolidin-3-amine (0.15 g, 0.53 mmol, 1 eq) in 1 mL of DMSO was added triethylamine (0.22 mL, 0.58 mmol, 1.1 eq) and HATU (0.22 g, 0.58 mmol, 3 eq). The mixture was stirred at room temperature for 1 h and was then concentrated and purified by HPLC to afford (S)—N-(1-(imidazo[1,2-a]pyrazin-8-yl)pyrrolidin-3-yl)-2-phenyl-2H-tetrazole-5-carboxamide (0.10 g, 0.26 mmol, 49%). 1H NMR (400 MHz, CD3OD) δ 8.19 (d, J=7.0 Hz, 2 H), 8.06 (s, 1 H), 7.95 (d, J=5.5 Hz, 1H), 7.82 (s, 1H), 7.70-7.58 (m, 3 H), 7.19 (d, J=5.8 Hz, 1 H), 5.00-4.90 (m, 1H), 4.80-3.80 (br, 4 H), 2.62-2.38 (m, 2 H); MS: (ES) m/z calculated for C18H17N9O [M+H]+ 376.2, found 376.
