実験手順
2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)biphenyl-4-carboxylic acid (EP 0533268 A1) was reacted with 3-(2-(t-butyloxycarbonylamino)ethoxy)-4-methoxyaniline (D11) following a procedure similar to that described in Example 1. The product was dissolved in methanol (10 ml), and treated with 3.3M ethereal HCl solution (3 ml) and left to stand at room temperature for 20 hours. After removal of the solvent in vacuo, the residue was dissolved in H2O solid potassium carbonate was added and the mixture extracted with EtOAC (3×). The combined organic extracts were dried and concentrated in vacuo. Flash column chromatography on silica gel eluting with 5% MeOH/CH2Cl2 gave the title compound as a white solid (0.06 g, 19%) mp 150°-153° C.
