実験手順

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 1-[2-(tert-butyl-dimethyl-silanyloxymethyl)-oxazol-4-yl]-ethanone (192 mg, 0.75 mmol) in dry THF (5.0 mL) was treated at rt with TBAF (1.1 mL of a 1M solution in THF, 1.10 mmol). The reaction mixture was stirred at rt for 1.5 h. The mixture was then diluted with EA (10 mL), washed with brine (3×10 mL), dried over Na2SO4, filtered and concentrated under reduced pressure. Purification of the residue by FC (1:1 to 2:1 EA-Hept) gave the title compound as a pale yellow solid. TLC: rf (EA)=0.37. LC-MS-conditions 02: tR=0.34 min, [M+H]+=142.46.
