2-Phenyl-ethanesulfonic acid (6-chloro-5-p-tolyl-pyrimidin-4-yl)-amide (850 mg) was added to a solution of K-tert. butylate (1.1 g) in ethylene glycol (15 ml). The mixture was stirred at 120° C. for 27 h before it was diluted with water (100 ml), acidified with 10% aq. citric acid (13 ml). The resulting precipitate was collected, washed with water and diethyl ether and dried to give 2-phenyl-ethanesulfonic acid [6-(2-hydroxy-ethoxy)-5-p-tolyl-pyrimidin-4-yl]-amide (716 mg) as a beige powder. LC-MS: tR=4.44 min, [M+1]+=414.18, [M−1]−=412.13.
