4-(2-Cyanopropan-2-yl)-N-(2-methyl-7-phenylpyrazolo[1,5-a]pyrimidin-5-yl)benzamide (Compound 343 (Example 357), 75 mg, 0.19 mmol) was dissolved in methanol (5 ml). The solution was subjected to hydrogenation conditions in a flow-hydrogenator, using Raney nickel cartridge, with 30 bar of hydrogen pressure, 50° C. temperature and a flow rate of 0.5 ml/min. The reaction mixture was concentrated in vacuo to obtain the titled product 4-(1-amino-2-methylpropan-2-yl)-N-(2-methyl-7-phenylpyrazolo[1,5-a]pyrimidin-5-yl)benzamide (45 mg, 59% yield). 1H NMR (CHLOROFORM-d) δ: 8.59 (br. s., 1H), 8.07-8.20 (m, 3H), 7.91 (d, J=8.3 Hz, 2H), 7.46-7.61 (m, 5H), 6.29 (s, 1H), 2.87 (br. s., 2H), 2.50 (s, 5H), 1.36 (s, 8H), 0.87 (br. s., 3H); ESI-MS: m/z 400.4 (M+H)+.
