반응 단계

To a solution of 5-methylisoxazol-3-ol (33.48 mg, 0.34 mmol) in acetonitrile (0.7 ml) potassium carbonate (60.85 mg, 0.44 mmol) was added followed by addition of methyl 2-(3-((methylsulfonyl)oxy)azetidin-1-yl)-5-(trifluoromethyl)nicotinate (D68) (120 mg, 0.34 mmol). The reaction mixture was heated at 180° C. under microwave irradiation for 25 min. After solvent evaporation the residue was purified by Biotage SNAP-Si column (10 g) eluting with cycloexane/ethyl acetate from 95/05 to 70/30. Collected fractions were evaporated in vacuo tot afford the title compound (D88) (20 mg)
