655225-01-7, A mixture of 4-bromo-6-hydroxypyrazolo[l,5-a]pyridine-3-carbonitrile (Intermediate PI, 200 mg, 0.840 mmol) in DMA (4.20 mL) was treated sequentially with K2CCb(s) (348 mg, 12.1 mmol) and tert-butyl 4-(2-bromoethyl)piperazine-l -carboxylate (493 mg, 1.68 mmol), then stirred for 3 h at 60 ¡ãC. After cooling to ambient temperature, the mixture was diluted with brine. The resulting suspension was filtered, and the solids were rinsed with water (5x). The solids the were collected, dissolved in DCM and concentrated in vacuo to cleanly afford the title compound (239 mg, 63percent yield). MS (apci) m/z = 452.0 (M+H).
655225-01-7 tert-Butyl 4-(2-bromoethyl)piperazine-1-carboxylate 15946441, apiperazines compound, is more and more widely used in various fields.
