5.88 g (47.7 mmol) isonicotinic acid and 7.74 g (47.7 mmol) 1,1′-carbonyldiimidazole in 30 mL DMF are stirred for 30 min at 45° C. prior to addition of 8.0 g (47.7 mmol) of 5-amino-2-chloro-pyrimidin-4-ol. The mixture is stirred for 12 h at rt, concentrated and purified by HPLC (reversed phase, water (+0.1% TFA)/MeOH) to yield N-(2-chloro-4-hydroxy-pyrimidin-5-yl)-isonicotinamide.
