実験手順

1,1-Dimethylethyl 3-[5-(5-{3-cyano-4-[(cyclopropylmethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-isoquinolinyl]propanoate (D48; 36 mg, 0.072 mmol) was dissolved in 4N HCl in 1,4-dioxane (4 ml) and the mixture was allowed to stand at room temperature for 4.5 h. The solvent was evaporated in vacuo and the residue triturated with dry ether to give a white solid which was dissolved in N-methyl-2-pyrrolidinone (1 ml) and purified by Mass Directed Preparative HPLC (Supelcosil ABZ+Plus column, eluting with solvents A/B (A: Water+0.1% Formic acid, B: MeCN:Water 95:5+0.05% Formic acid)). The solvent was dried under a stream of nitrogen to give the title compound as a white solid (10.5 mg)
