Procedure

The title compound was prepared using the method of Example 34(d) starting from (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (200 mg, 0.767 mmol) and 6,7-dihydro-4H-pyrazolo[5,1-c][1,4]oxazine-2-carboxylic acid (166 mg, 0.997 mmol). The product was triturated with acetonitrile. Yield 95 mg (46%). 1H-NMR (400 MHz; d6-DMSO): δ 1.09 (d, 3H), 4.09 (t, 2H), 4.18 (t, 2H), 4.26-4.39 (m, 2H), 4.42-4.49 (m, 1H), 4.79 (s, 2H), 6.38 (s, 1H), 6.95 (d, 1H), 7.82 (d, 1H), 7.97-7.99 (m, 2H), 8.09 (s, 1H), 8.26 (d, 1H).
