실험 절차

A reaction tube charged with 6-chloro-5-(4-chloro-phenyl)-1-phenyl-1,5-dihydro-pyrazolo[3,4-d]pyrimidin-4-one (20.0 mg, 0.056 mmol) and Pd(PPh3)4 (6.5 mg, 0.0056 mmol) is purged with nitrogen. A solution of 2-tributylstannanyl-benzothiazole (47.6 mg, 0.112 mmol) in anhydrous toluene (1.0 mL) is added via syringe. The reaction mixture is heated at 100° C. for 2 days. After removal of the solvent, the residue is purified by preparative LCMS to provide the title compound; 1H NMR (CDCl3, 400 MHz) δ 8.36 (s, 1H), 8.21 (d, 2H), 7.90 (t, 1H), 7.69 (t, 1H), 7.59 (t, 2H), 7.46-7.40 (m, 5H), 7.24 (d, 2H); HPLC-MS calculated for C24H14ClN5OS (M+H+) 456.1. Found 456.1.
