Reaction Steps

2-Amino-5-[4-(3-fluorooxetan-3-yl)phenyl]thiophene-3-carboxamide (88 mg, 0.301 mmol), 1-[(6-bromopyridin-2-yl)methoxy]-2-methylpropan-2-ol (Example 217 Step 1) (78 mg, 0.301 mmol), Pd2dba3 (27.6 mg, 0.030 mmol), K2CO3 (45.8 mg, 0.331 mmol) and X-Phos (71.8 mg, 0.151 mmol) were added to a 5 mL microwave vial. Degassed tert-amyl alcohol (0.6 mL) was added and the vial evacuated and back-filled with N2 (3×). The resulting mixture was stirred at 100° C. overnight. After cooling to room temperature, the mixture was diluted with methanol, silica gel was added, and the solvent was removed in vacuo. Purification of the residue by flash chromatography (silica, 0-10% MeOH-DCM) followed by flash chromatography (silica, 12-100% EtOAc-hexanes) gave the title compound as a pale yellow solid.
