To a solution of methyl 4-(1-(5-chloro-2-(3-((3-fluorophenoxy)methyl)pyrrolidin-1-yl)nicotinamido)cyclopropyl)benzoate (D200) (37 mg, 0.070 mmol) in a mixture 1,4-dioxane and water (3:1) (2 ml) lithium hydroxide monohydrate (10 mg, 0.238 mmol) was added and the mixture was stirred 20 min (4 cycles of 5 min each) under microwaves irradiation. After solvent evaporation the residue was diluted with water (5 ml) and 1M HCl (5 ml) and extracted with ethylacetate (3×10 ml). Collected organics after solvent evaporation afforded a residue that was purified by ISOLUTE Spe-Si (1 g) eluting with a mixture dichloromethane/methanol 98:2. Collected fractions after solvent evaporation afforded the title compound (E76) (18.2 mg)
