Reaction Steps

To a solution of 5-chloro-N-(2-(isopropylsulfonyl)phenyl)pyrazolo[1,5-a]pyrimidin-7-amine (0.1 mmol) and 2-isopropoxy-5-methyl-4-(piperidin-4-yl)aniline (0.1 mmol) in 2 mL of isopropanol, was added 25 uL of HCl in dioxane (2 N). The suspension was stirred at 150° C. for 3 hours. After work-up and prep-HPLC, product was obtained. 1H NMR (CDCl3, 400 MHz) δ 7.88-7.95 (m, 3H), 7.73-7.75 (d, 1H), 7.61-7.64 (m, 1H), 7.23-7.26 (m, 1H), 6.88 (s, 1H), 6.75 (s, 1H), 6.17-6.18 (d, 1H), 6.09 (s, 1H), 4.46-4.54 (m. 1H), 3.30-3.34 (m, 2H), 3.12-3.21 (m, 1H), 2.79-2.83 (m, 3H), 2.27 (s, 3H), 1.77-1.79 (m, 4H), 1.15-1.28 (m, 12H); MS (ES+): 563.28 (M+1)+.
