Reaction Steps

To a degassed solution of 3-pyridylcarbinol (17.6 mg, 0.16 mM, 1.5 equiv) in 0.8 mL of DMF was added a one molar solution of lithium hexamethyldisilazide (215 uL, 0.22 mM, 2.0 equiv). This mixture was stirred for 10 minutes then added dropwise to a stirred solution of 5-chloro-N-isopropylpyrazolo[1,5-c]pyrimidine-3-carboxamide (25.7 mg, 0.11 mM, 1.0 equiv) in one mL of DMF. The reaction mixture was purified using reversed phase HPLC (5 to 30% acetonitrile/water, 0.1% formic acid) and the product lyophilized to give 22.7 mg (68%) of N-isopropyl-5-(pyridin-3-ylmethoxy)pyrazolo[1,5-a]pyrimidine-3-carboxamide. LCMS (ESI) m+H=312.2, 1H NMR (400 MHz, DMSO-d6) δ: 9.09 (d, 1H), 8.76 (d, 1H), 8.59 (dd, 1H), 8.38 (s, 1H), 7.95 (d, 1H), 7.45 (dd 2H), 6.81 (d, 1H), 5.61 (s, 1H), 4.08 (m, 1H), 1.19 (d, 6H).
