57.5 mg (0.19 mmol) of 4-(3-chloroanilino)-6-(thiocarbamoyl)-7H-pyrrolo[2,3-d]pyrimidine (see Example 10) in 3 ml of methanol and 57.3 mg (0.25 mmol) of 4-methoxyphenacyl bromide are heated to boiling for 17 h. Cooling of the pale yellow suspension, filtering and washing with isopropanol/diethyl ether yields 4-(3-chloroanilino)-6-[4-(4-methoxyphenyl)thiazol-2-yl]-7H-pyrrolo[2,3-d]pyrimidine; HPLC: tRet(Grad20)=15.4; TLC-Rf=0.33 (CH2Cl2/methanol=10:1); FAB-MS: (M+H)+=434.
