Reaktionsschritte

To a solution of 3-(5-amino-6-methyl-2-pyridinyl)-1,3-oxazolidin-2-one (80 mg, 0.414 mmol) in dichloromethane (3 mL) and pyridine (0.033 mL, 0.414 mmol) was added 4-{[(3,5-dimethyl-4-isoxazolyl)methyl]oxy}benzenesulfonyl chloride (125 mg, 0.414 mmol). The reaction vessel was sealed and heated at 65° C. for 6 hours. The reaction mixture was then allowed to cool and separated between dichloromethane (40 mL) and saturated sodium bicarbonate solution (30 mL). The organic phase was separated using a hydrophobic frit and evaporated in vacuo. The crude was then purified by flash silica (Si) chromatography (0-100% ethyl acetate-cyclohexane gradient). The appropriate fractions were combined and evaporated in vacuo to give the title compound (137 mg) as a colourless glassy solid. LCMS (2 min, formic) Rt 0.92 min, m/z (ES+) 459 (M+H).
