Reaction Steps

Analogously to Step 8.3,1.45 g of 6-(4-ethoxycarbonyl-phenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-ol in 15 ml of phosphorus oxychloride are heated under a protective gas for 2 hours and worked up, yielding the title compound; m.p.: 250° C. (decomp.): TLC-Rf =0.63 (ethyl acetate/hexane [1:1]); FAB-MS: (M+H)+ =302.
