Acetic Acid → 7-(Hydroxymethyl)-2,3-dihydro-5(1H)-indolizinone

Participants

Reaction Steps

A solution of 7-({[(1,1-dimethylethyl)(dimethyl)silyl]oxy}methyl)-2,3-dihydro-5(1H)-indolizinone (3.93 g, 14.09 mmol) in tetrahydrofuran (100 ml) was treated with acetic acid (1.61 ml, 28.17 mmol) and tetrabutylammonium fluoride (1M in THF, 21 ml, 21.13 mmol) and stirred at room temperature for 1 h before being evaporated. The residue was chromatographed on silica eluting with 0-20% methanol in dichloromethane to give the desired product (1.87 g, 80%)
