Reaction Steps

To 1-(2-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-4,5-dihydronaphtho[2,1-d]thiazol-7-yl)ethane-1,2-diol (Example 83, 0.233 g, 0.508 mmol) in THF (3 mL) was added sodium periodate (0.163 g, 0.762 mmol) in 2 mL of water over a period of 2 min. at room temperature and the contents stirred at room temperature for 30 min. The reaction mixture was partitioned between EtOAc (60 mL) and water (20 mL). The EtOAc layer was concentrated, the yellow solid that was obtained was azeotroped with acetonitrile (20 mL), dried under a high vacuum. Yield: (183 mgs, 83%); LC/MS M+1=427.
