実験手順
(R)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (86 mg, 0.33 mmol) was coupled with 5-methoxythiazole-2-carboxylic acid (90 mg, 0.40 mmol) using the method of Example 34(d). Crude product was purified by CombiFlash (column: silica, eluent: 0-10% MeOH in DCM) to yield 12 mg (9%) of the title compound. 1H-NMR (400 MHz; CDCl3): δ 1.23 (d, 3H), 3.99 (s, 3H), 4.26 (dd, 1H), 4.40-4.46 (m, 1H), 4.49-4.59 (m, 1H), 6.63 (d, 1H), 7.22 (s, 1H), 7.49 (d, 1H), 7.68 (d, 1H), 7.78 (dd, 1H), 8.10 (broad d, 1H) overlapping with 8.13 (d, 1H).
