Versuchsvorschrift

To a solution of 4-{[(3,5-dimethyl-4-isoxazolyl)methyl]oxy}-N-{2-methyl-6-[1-(phenylmethyl)-3-pyrrolidinyl]-3-pyridinyl}benzenesulfonamide (211 mg, 0.396 mmol) and N″-(1,1-dimethylethyl)-N,N,N′,N′-tetramethylguanidine (67.9 mg, 0.396 mmol) in acetonitrile (3 mL) was added 1-bromo-2-methylpropane (0.086 mL, 0.792 mmol). The reaction vessel was sealed and heated at 80° C. for 8 hours. The reaction mixture was separated between ethyl acetate and saturated sodium bicarbonate solution. The organic phase was washed with brine and dried over magnesium sulphate. The solvent was removed 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 required product (114 mg) as a brown gum. LCMS (2 min, formic) Rt 1.01 min, m/z (ES+) 589 (M+H)
