Reaction Steps

To 465 mg (2.00 mmol) of 3-bromo-5-chloropyrazolo[1,5-a]pyrimidine was added tert-butyl (2-aminoethyl)(methyl)carbamate (522 mg, 3.00 mmol), 4 mL of isopropanol, and triethylamine (0.56 mL, 4.00 mmol). The resulting mixture is heated at 140° C. for 0.5 hr in the microwave. It was diluted with EtOAc, and washed with water and brine. The organic layer was dried over MgSO4, concentrated and purified on the silica gel column eluting with 20-100% EtOAc/Hex to obtain 607 mg (82%) of the desired product.
