Source of material
An oven-dried round bottom flask was charged with a stirring bar, 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxamide (100 mg, 0.5 mmol), 5-(tert-butyl)-1H-pyrazol-3-amine (70 mg, 0.5 mmol), cesium carbonate (500 mg, 1.5 mmol), and DMF (5 mL), and then the reaction mixture was stirred at 120 °C under nitrogen atmosphere for 8 h [5]. The product was obtained by column chromatography eluting with dichloromethane and methanol 15:1. The resulting solution was evaporated to get some colorless crystals.
Experimental details
All hydrogen atoms were placed in the calculated positions and all the non-hydrogen atoms were refined anisotropically.
Comment
Derivatives similar to the title compound have been reported to have antitumor activity, anti pulmonary fibrosis activity and janus kinase protein inhibitory activity [6], [7], [8], [9], [10]. Exactly the same skeleton as the title compound has not been reported in the literature, which may arouse the interest of researchers.
The asymmetric unit of the title structure contains two molecules 9-(tert-butyl)-3,11-dihydro-6H-pyrazolo [1,5-a]pyrrolo[3′,2′:5,6]pyrido[4,3-d]pyrimidin-6-one molecules and a water molecule. There is a disorder of the t-butyl group and the ratio is 0.552:0.448. All other values of the geometric parameters are normal. The bond lengths and angles are in the expected ranges.
