2,6-Lutidine → 1-Benzyloxymethyl-5-[(3-benzyloxy-4-nitrophenyl)-(tert-butyldimethylsilanyloxy)-methyl]-1h-pyrazole

Participants

Reaction Steps

A mixture of (2-benzyloxymethyl-2H-pyrazol-3-yl)-(3-benzyloxy-4-nitrophenyl)-methanol (392 mg, 0.881 mmol), TBSOTf (0.25 mL, 1.09 mmol) and 2,6-lutidine (0.153 mL, 1.32 mmol) in CH2Cl2 is stirred at RT for 2 h. The mixture is partitioned between CH2Cl2 and aqueous NaHCO3. The organic phase is dried over MgSO4 and concentrated. The residue is purified by flash chromatography to give the title compound.
