Yield:1131992-13-6 96%
Reaction Conditions:
with N-Bromosuccinimide in dichloromethane at 20;
Steps:
Step 2
Step 2: To a stirred solution of 2,4-dichloro-7-methyl-7/-/-pyrrolo[2,3-c]pyrimidine (2.06 g, 10.198 mmol) in dichloromethane (20 mL) was added /V-bromosuccinimide (2.17 g, 12.237 mmol) in one portion at room temperature, and the reaction was stirred overnight. The reaction mixture was concentrated and water was added to the residue. The precipitated solid was filtered and dried under vacuo to obtain 5-bromo-2,4-dichloro-7-methyl-7/-/-pyrrolo[2,3- cdpyrimidine as an off white solid (2.76 g, 96 %). LCMS (ES) m/z = 279.9, 281.9 [M+H]+. H NMR (400 MHz, DMSO-d6) δ ppm 3.84 (s, 3H), 7.24 (s, 1 H).
