Procedure

To a stirred solution of 1-[2-methoxypyridin-4-yl]-1-[1-(pyridin-3-yl)indazol-5-yl]oxypropan-2-amine (41 mg, 110 μmol) in dichloromethane (4 ml) was added triethylamine (36 μl), followed by cyclopropanesulfonic acid chloride (23 mg, i 60 μmol) and DMAP (1.3 mg, 11 μmol).The stirring was continued for 20 h at room temp. The reaction mixture was poured into sat. NH4Cl solution and extracted with dichloromethane then the solvent was removed i.vac., and the product purified by chromatography on silica gel. Yield 4 mg (7.6%) as a racemic mixture of one diastereomer.
