Reaction Steps

A mixture of methyl 4-(5-(2-(2-tert-butylphenoxy)pyridin-3-ylamino)-1,3,4-thiadiazol-2-yl)-4-methylpentanoate (Example 96) (450 mg, 1.0 mmol), lithium hydroxide hydrate (125 mg, 3 mmol) in THF (10 mL) and water (2 mL) was stirred at rt for 2 h. A solution of saturated ammonium chloride was added and mixture was extracted twice using ethyl acetate. The organic phase was separated, dried (MgSO4), filtered and evaporated. The crude material was purified by preparative HPLC to give the title compound (430 mg, TFA salt) as a white solid. (M+H)+=441.
