Reaction Steps

4-methyl-2-(pyridin-3-yl)-1H-imidazole-5-carboxylic acid (78 mg; 0.384 mmol) and DIPEA (0.20 ml, 1.151 mmol) were dissolved in 5 ml of dry DMF. HOBt hydrate (88 mg; 0.575 mmol) and EDCI (110 mg; 0.575 mmol) were added at RT. Solid (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (100 mg; 0.384 mmol) was added in one portion and the reaction was stirred for 2 h at 60° C. temperature and stirred at RT overnight. Water (40 ml) was added and the mixture was allowed to stir 1 h at RT. The precipitated product was filtered, dried in vacuum at 40° C. for 12 h, to give the title compound 136 mg. 1H-NMR (400 MHz; d6-DMSO): δ 1.12 (d, 3H), 2.49 (s, 3H), 4.40 (m, 3H), 6.97 (d, 1H), 7.48 (m, 1H), 7.88 (m, 2H), 8.02 (m, 2H), 8.07 (d, 1H), 8.21 (m, 1H), 8.58 (m, 1H), 9.13 (d, 1H), 12.85 (s, 1H).
