実験手順

57.5 mg (0.19 mmol) of 4-(3-chloroanilino)-6-(thiocarbamoyl)-7H-pyrrolo[2,3-d]pyrimidine (see Example 10) and 34 ml of 1-bromo-2-butanone (Aldrich; Milwaukee/USA) in 3 ml of dioxane are heated to boiling for 2 h. Cooling, filtering the suspension and washing with isopropanol/diethyl ether yields 4-(3-chloroanilino)-6-(4-ethylthiazol-2-yl)-7H-pyrrolo[2,3-d]pyrimidine; HPLC: tRet(Grad20)=13.6; FAB-MS: (M+H)+=356.
