Versuchsvorschrift

A mixture of 1-(2-thiazolyl)ethanol (1.17 g, 8.67 mmole) and ethyl bromoacetate (1.32 g, 8.63 mmole) was heated at 48 C for 18 hr. The reaction mixture was dissolved in acetonitrile (3 mL) and stored at 4 C. After 2 months the crystals which separated were filtered out and washed with 3:7 ether-acetonitrile to yield 2.028 g of the title compound, mp 101–103 C.
