Procedure

To a solution of N-(2-methylpropyl)-2-(trifluoromethyl)-4-pyrimidinamine (100 mg, 0.456 mmol) and 4-{[(3,5-dimethyl-4-isoxazolyl)methyl]oxy}benzenesulfonyl chloride (151 mg, 0.502 mmol) in pyridine (1 mL) was added 2-(tert-butyl)-1,1,3,3-tetramethylguanidine (0.092 mL, 0.456 mmol). The reaction vessel was sealed and heated by microwaves to 100° C. for 30 minutes. The solvent was evaporated in vacuo to give the crude product, which was purified by solid phase extraction (SPE) using an aminopropyl (NH2) cartridge then a sulphonic acid (SCX) cartridge (both eluted with methanol). The appropriate fractions were combined and dried under a stream of nitrogen to give the crude product which was further purified by mass directed autoprep (formic acid modifier) to give the title product, 19.8 mg. LCMS (2 min, formic) Rt 1.32 min, m/z (ES+) 485 (M+H).
