Reaction Steps

To a stirred solution of (R)-5-(1-(benzyloxy)ethyl)-1,3,4-oxadiazol-2(3H)-one (44 mg, 0.2 mmol), 3-(6-phenylpyridin-3-yl)-5-(piperidin-4-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (150 mg, 0.24 mmol) and DIEA (70 ul, 0.4 mmol) in DMF (1.4 mL) was added BOP (97 mg, 0.22 mmol) and the resulting solution was allowed to stir overnight. Water was added and was extracted with EtOAc (3×) and combined organic layers were washed with water (3×), brine once and dried (MgSO4). After concentration in vacuo the residue was purified on silica gel. Elution with EtOAc/Hexanes (0-10%) gave the title compound (142 mg, 85%).
