Vorschrift

To a suspension of N-[7-(4-bromoanilino)-4,5-dihydro[1,3]thiazolo[4′,5′: 3,4]benzo[d][1,3]thiazol-2-yl]-N′-ethylurea (27 mg, 0.060 mmol) in toluene (2.0 mL) was added DDQ (28 mg, 0.125 mmol). The reaction mixture was stirred at about 20° C. for about 2 hrs. The reaction mixture was pumped down in vacuo and purified by preparative HPLC. 7 mg (26%, 2 steps) pure product was isolated. LC/MS 448 and 450 (MH+); RP-HPLC 18.09 min.
