Versuchsvorschrift

A mixture of 2-amino-5-methylthiazole (1.2 g, 11 mmol) and 2-(bromomethyl)tetrahydro-2H-pyran (1.5 mL, 12 mmol) was warmed to 85° C. and stirred for 18 hours. The mixture was cooled to ambient temperature and purified via flash column chromatography (SiO2, 10% methanol in ethyl acetate then 9:1:0.1 CH2Cl2:methanol:NH4OH) to afford the title compound. MS (DCI/NH3) m/z 213 (M+H)+.
