Reaction Steps

A suspension of N-(7-chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-4-(2-hydroxypropan-2-yl)benzamide (2F, 80 mg, 0.232 mmol), 3-(dimethylamino)phenylboronic acid (49.8 mg, 0.302 mmol), and 1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (17 mg, 23 μmol) in 2:1 1,4-dioxane/saturated aqueous NaHCO3 (0.774 mL of 1,4-dioxane and 0.387 mL of saturated aqueous NaHCO3) was prepared in a 10 mL microwave reaction vessel and the sealed reaction vessel warmed to 110° C. for 10 minutes in a CEM microwave reactor. The reaction mixture was cooled to rt, diluted with methanol, filtered, and purified via preparative HPLC (35-40% MeCN/H2O gradient+0.01% TFA). Lyophilization of the combined fractions gave the titled compound as a yellow solid (25.4 mg, 26%). 1H NMR (DMSO-d6) δ: 11.09 (s, 1H), 7.90-7.98 (m, 2H), 7.86 (s, 1H), 7.48-7.60 (m, 2H), 7.31-7.38 (m, 1H), 7.28-7.32 (m, 1H), 7.19 (d, J=8.1 Hz, 1H), 6.92 (dd, J=8.1, 2.3 Hz, 1H), 6.30 (s, 1H), 2.91 (s, 6H), 2.33 (s, 3H), 1.39 (s, 6H); ESI-MS: m/z 430.3 (M+H)+.
