- Difficulties encountered in the preparation of pure trisformylmethane ted to the (successful) use of the crude reaction mixture in these and similar condensation reactions (ref. 1). In fact, the pure material failed to cyclize with 2,4,6-triaminopyrimidine to give 2,4-diamino-6-formyl-5-deazapteridine (ref. 2), although impure trisformylmethane reacted satisfactorily (ref. 1)
