Reaction Steps

A solution of (R)-1-(5-(4-(2-hydroxypropan-2-yl)benzamido)pyrazolo[1,5-a]pyrimidin-7-yl)piperidine-3-carboxylic acid (Compound 84, 100 mg, 0.236 mmol), dimethylamine (236 μL, 0.472 mmol), EDCI (90 mg, 0.472 mmol), and HOBT (16 mg, 0.118 mmol) in DMF (4 mL) were stirred for 12 hours at room temperature. The reaction was complete as determined by LCMS analysis. The reaction mixture was then partitioned between ethyl acetate and water and the separated organic layer was dried over Mg2SO4, filtered, and concentrated under reduced pressure. Purification by preparatory HPLC, 20-40% (MeCN/H2O gradient+0.01% TFA) provided the titled compound as a white solid (71 mg, 69%). 1H NMR (DMSO-d6) δ: 10.91 (s, 1H), 8.08 (d, J=2.3 Hz, 1H), 7.95-8.03 (m, J=8.6 Hz, 2H), 7.60 (d, J=8.8 Hz, 2H), 7.37 (s, 1H), 6.36 (d, J=2.0 Hz, 1H), 4.55 (br. s., 1H), 4.35 (br. s., 1H), 2.97-3.18 (m, 6H), 2.83 (s, 3H), 1.57-2.01 (m, 4H), 1.45 (s, 6H). ESI-MS: m/z 451.0 (M+H)+.
