Procedure

2-Phenyl-ethanesulfonic acid (6-chloro-2-pyridin-4-yl-5-p-tolyl-pyrimidin-4-yl)-amide (480 mg) was added to a solution of K-tert. butylate (580 mg) in ethylene glycol (5 ml). The mixture was stirred at 11° C. for 72 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)-2-pyridin-4-yl-5-p-tolyl-pyrimidin-4-yl]-amide as a beige powder. LC-MS: tR=4.17 min, [M+1]+=491.24, [M−1]−=489.08.
