Reaction Steps
Temozolomide (0.200 g; 1.03 mmol) and 2-bromoacetophenone (0.246 g; 1.24 mmol) were stirred in a sealed tube under nitrogen, and heated to 130° C. for 1 hour. The mixture was cooled, and then concentrated in vacuo before being applied directly to the head of a chromatography column (SiO2) and purified by column chromatography (DCM:MeOH, 5:1), to give the title compound as a yellow powder (0.003 g; 1%). δH (DMSO-d6) 8.97 (1H, s), 8.88 (1H, s), 7.91 (2H, t, J=7.4), 7.50 (2H, t, J=7.4), 7.39 (1H, t, J=7.4), 3.90 (3H, s).
