In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 5-(((tert-butyldimethylsilyl)oxy)methyl)-2-(methoxymethyl)thiazole (721 mg, 2.64 mmol) in THF (20 mL) was treated at 0° C. with TBAF (5.30 mL of a 1M solution in THF, 5.30 mmol) and the resulting mixture was stirred for 45 min at 0° C. The reaction mixture was diluted with EA, washed with sat. aq. NH4Cl and brine, dried over Na2SO4, filtered and the solvent was removed under reduced pressure. Purification of the residue by FC (1:9 hept-EA) gave the title compound as a colorless oil: TLC: rf (1:9 hept-EA)=0.27. LC-MS-conditions 07: tR=0.41 min, [M+H]+=160.01.
