Reaktionsschritte

To a DCM solution of thiazol-4-ylmethanol (Combi-Blocks)(1 g, 8.69 mmol) stirred at 0° C., were added TIPSCl (2.2 mL, 10.43 mmol) and imidazole (1.48 g, 21.72 mmol). The resulting mixture was then warmed to room temperature and stirred for overnight. The reaction was quenched with saturated aqueous NH4Cl solution, extracted with ethyl acetate three times. The combined organic layers were washed with brine, dried with anhydrous Na2SO4, concentrated to a residue which was purified by flash column to give 4-((triisopropylsilyloxy)methyl)thiazole (2 g). 1H NMR (300 MHz, CDCl3), d: 8.794 (m, 1H), 7.338 (m, 1H), 5.065 (s, 2H), 1.209 (m, 3H), 1.133 (d, J=6 Hz, 18H).
