Source of material
A suspension of methyl 2-(4-(3-bromopyrazolo[1,5-a]pyrimidin-6-yl)phenyl)acetate (692 mg, 2 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (416 mg, 2 mmol), potassium phosphate (636 mg, 3 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (146 mg, 0.2 mmol) in dioxane (5 mL) and water (1 mL) was sealed, degassed by nitrogen and heated under microwave irradiation at 120 °C for 30 min. The reaction mixture was diluted with dichloromethane (20 mL) and washed with water and brine. The organic phase was dried over MgSO4 and concentrated. The raw product was purified by column chromatography over silica gel eluting with a gradient of methanol/dichloromethane (v/v, 0−3%) to afford the light yellow solid. Yield, 437 mg, 63%. The title compound was dissolved in dichloromethane, and the solvent was evaporated slowly at room temperature. After three days, light yellow crystals suitable for X-ray diffraction analysis were obtained.
Experimental details
Data reduction was carried out using the Bruker software APEX2 including SADABS [1]. The structure was determined by the intrinsic phasing routines in the SHELXT program [2] and refined by full-matrix least-squares methods in SHELXL [3] using Olex2 [4]. All of hydrogen atoms were placed in the calculated positions and all the non-hydrogen atoms were refined anisotropically. The R1 factor for all reflections and the Rint factor are both enlarged, as the ratio of observed/unique reflections is low (44%).
Comment
Pyrazolo[1,5-a]pyrimidine scaffold, as a multifunctional structure, is widely used in organic chemistry, drug synthesis and food chemistry and so on [5], [6], [7], [8]. In addition, aryl bromides are very important pharmaceutical intermediates, which can be easily used in many coupling reactions. For example the brominated pyrazolo[1,5-a]pyrimidine derivatives are key intermediates to synthesize AMPK inhibitors in anticancer field [9], [10]. In this work, we describe the synthesis of methyl 2-(4-(3-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidin-6-yl)phenyl)acetate in good yield by coupling reaction of methyl 3-(4-(3-bromopyrazolo[1,5-a]pyrazin-6-yl)phenyl)propanoate with 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole, this compound will be used for the development of novel AMPK inhibitors. The NMR results are consistent with the crystal structure of methyl 2-(4-(3-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidin-6-yl)phenyl) acetate. The bond lengths and angles in both crystallographically independent molecules are in the normal ranges [11]. In a word, methyl 2-(4-(3-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidin-6-yl)phenyl)acetate was synthesized under a mild condition, which can be readily used to synthesize a diverse range of AMPK inhibitors for the development of anticancer drugs.
