Versuchsvorschrift
A microwave vial was charged with the product of Step 2 (50 mg, 0.094 mmol), MeOH (666 μl) and then NaOH (700 μl, 0.700 mmol). The mixture was irradiated in the microwave for 20 minutes at 100° C. The pH was adjusted to 3-4 with 1M HCl, then diluted with water and extracted with 10% IPA/CHCl3. The combined organics were washed with water, dried (NaSO4), filtered and concentrated to afford racemic-4-{1,2-dihydroxy-1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]ethyl}benzoic acid (33.4 mg, 0.065 mmol, 68.6% yield).
