Procedure

To a stirred solution of 1,1-carbonyldiimidazole (31 mg, 190 Amok) in THF (1 ml) was added (2R)-2-hydroxypropanoic acid (18 mg, 20 μmol) to give a colorless solution. The reaction mixture was stirred for 1 h at r.t. Then a solution of (1R,2S)-1-{[1-(4-fluorophenyl)-1H-indazol-5-yl]oxy}-1-(3-methoxyphenyl)propan-2-amine (6a, 39 mg, 100 μmol) in THF (0.5 ml) was added, and the stirring was continued at r.t. overnight. The solvent was removed in vacuo, the residue dissolved in acetonitrile/water mixture, and the crude product purified by preparative HPLC. Yield 16 mg (35%).
