2-Iodo-6-methyl-pyridin-3-ol (6.49 g, 27.6 mmol) was stirred in a 1M solution of sodium hydroxide (30 ml). To this was added 1-bromoethan-2-ol (3.91 ml, 55.20 mmol) dropwise at room temperature. The resulting solution was then heated to 100° C. and stirred for 2 hours. The reaction mixture was cooled and then extracted into chloroform (2×100 ml). The organic phases were combined and extracted with a solution of 1M sodium hydroxide (25 ml). The organic phase was then dried over magnesium sulfate and concentrated in vacuo. This provided the desired product which was used without further purification (5.26 g).
