실험 절차

The compound was prepared using the method of Example 34(d). (S)-4-(1-(2-amino-propyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (1.00 g; 3.84 mmol), 2-aminothiazole-4-carboxylic acid (0.66 g; 4.66 mmol), 1.00 ml of DIPEA, HOBt (0.26 g; 1.9 mmol) and EDCI (1.10 g; 5.75 mmol) were used as starting materials. Purification by isopropanol:toluene crystallization afforded 0.93 g (63%) of the title compound. 1H-NMR (400 MHz; d6-DMSO): δ 1.10 (d, 3H), 4.22-4.45 (m, 3H), 6.96 (d, 1H), 7.04 (broad s, 2H), 7.15 (s, 1H), 7.82 (d, 1H), 7.90 (d, 1H), 7.97 (s, 1H), 8.08 (s, 1H).
