実験手順

6-Bromo-1-hydroxyisoquinoline (150 mg, 0.67 mmol, 1.0 equiv), tetrabutylammonium bromide (25 mg, 0.07 mmol, 0.1 equiv), and 1-bromo-2-phenylpropane (160 uL, 0.8 mmol, 1.2 equiv) were combined in toluene (10 mL) and treated with 50% aq. NaOH (2 mL), and the resulting mixture was stirred rapidly at ambient temperature for 48 hours, then heated at 60° C. for 24 h. The mixture was diluted with diethyl ether and washed with water and brine. The organic phase was dried over Na2SO4. Concentration and purification of the residue using silica gel flash chromatography (2-12% EtOAc/hex.) gave white crystals of 6-bromo-2-(2-phenylpropyl)-isoquinolin-1-one (169 mg, 0.49 mmol, 74%). This isoquinolinone (169 mg, 0.49 mmol) was converted, via Methods 1 and 2, to compound 5 (65 mg, 43%) which was isolated as white solid. [M−H]−=306.1 m/z. Activity: B
