Reaction Steps

A mixture of 3-(1-methylethyl)-1,2-benzisoxazol-4-ol and 2-(1-methylethyl)-1,3-benzoxazol-4-ol (Intermediate 40, 13 mg), was dissolved in DMF (2.0 mL) and 2-chloro-5-nitropyridine (11.6 mg, 0.073 mmol) was added, followed by potassium carbonate (30 mg, 0.22 mmol). The reaction mixture was heated under microwave irradiation at 110° C. for 1 hour. After the removal of the volatiles, the residue obtained was charged on a silica gel column (Biotage SP1 system) and eluted with Cyhexane/EtOAc (from 10/0 to 9/1, then 9/1, then from 9/1 to 8/2) to afford the title compound (8.7 mg).
