Versuchsvorschrift

To a solution of 2-methyl-6-[1-(phenylmethyl)-3-pyrrolidinyl]-3-pyridinamine (150 mg, 0.561 mmol) in dichloromethane (DCM) (4 mL) and pyridine (0.045 mL, 0.561 mmol) was added 4-{[(3,5-dimethyl-4-isoxazolyl)methyl]oxy}benzenesulfonyl chloride (169 mg, 0.561 mmol). The reaction vessel was sealed and heated at 65° C. for 2 hours. Additional 4-{[(3,5-dimethyl-4-isoxazolyl)methyl]oxy}benzenesulfonyl chloride (169 mg, 0.561 mmol) and pyridine (0.045 mL, 0.561 mmol) were added and the reaction mixture was heated for a further 4 hours at 65° C. The reaction mixture was then cooled and separated between DCM (40 mL) and saturated sodium bicarbonate solution (30 mL). The organic phase was passed through a hydrophobic frit and evaporated in vacuo. The sample was purified by flash silica (Si) chromatography (0-25% methanol-dichloromethane gradient). The appropriate fractions were combined and evaporated in vacuo to give the title product (211 mg) as a brown gum (approx 71% pure). LCMS (2 min, formic) Rt 0.80 min, m/z (ES+) 533 (M+H)
