Participants

Reaction Steps

To a stirred solution of 1-[6-methoxypyridin-3-yl]-1-[1-(pyridin-2-yl)indazol-5-yl]oxypropan-2-amine (50 mg, 130 μmol) in dichloromethane (5 mL) was added triethylamine (44 μl), followed by cyclopropane sulfonic acid chloride (28 mg, 200 μmol) and DMAP (1.6 mg, 13 μmol).The stirring was continued for 20 min 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 24 mg as a racemic mixture of two diastereomeres (37%).
