Tetrahydrofuran → 2-(2-benzyl-3-phenyl-2H-indazol-7-yl)propan-2-ol

Participants

Reaction Steps

Ninety milligrams (90 mg; 0.24 mmol) of 2-benzyl-3-phenyl-2H-indazole-7-carboxylic acid methyl ester, prepared from 2-benzyl-3-phenyl-2H-indazole-7-carboxylic acid (see preparation of Example 518), were dissolved in THF and 0.5 ml of 3M MeMgBr in THF (1.4 mmol) were added. The reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was quenched with aq NH4Cl solution and product was extracted with EtOAc, and then flash column chromatography (SiO2, dichloromethane as an eluant) afforded 2-(2-benzyl-3-phenyl-2H-indazol-7-yl)propan-2-ol in 86% yleld.
