Versuchsvorschrift

A suspension of 6-chloro-9-(4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-9H-purin-2-ylamine (80 mg, 0.25 mmol) in acetic acid anhydride (2.2 g) was treated with one drop of concentrated H2SO4 and stirred at r.t. for 5 min. Work-up (EtOAc), drying (MgSO4) and evaporation gave the title compound as a white solid. HPLC Rt: 4.093 min. 1H-NMR (CDCl3): δ 8.20 (s, 1H), 8.10 (s, 1H), 5.46 (s, 2H), 3.78 (s, 3H), 2.54 (s, 3H), 2.38 (s, 3H), 2.27 (s, 3H).
