Versuchsvorschrift

Treat a solution of 3-(2-chloro-4-hydroxy-benzyl)-1-(4,5,6,7-tetrahydro-2H-indazol-5-yl)-pyrrolidin-2-one (0.2 g, 0.58 mmol) and 2-Iodopropane (0.06 mL, 0.64 mmol) in DMF (4 mL) with potassium carbonate (0.1 g, 0.7 mmol) and stir reaction overnight at room temp. Quench the reaction with 1N HCl and extract with EtOAc. Wash the organic with brine, dry over MgSO4, filter, and remove the solvent. Purify the crude by silica gel column chromatography and remove the solvent to afford 0.11 g (48%) of product. MS (m/e): 388 (M+1).
