実験手順

To a solution of 1.5 g of 4-Hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid butyl ester, Example A-65.f, in 6.3 ml of anhydrous DMF was added 578 mg of dimethylthiocarbamoylchloride and 1.5 g of 1,4-diazabicyclo[2.2.2]octane. The mixture was stirred overnight at room temperature. The mixture was poured into 30 ml of 1 N HCl and extracted three times with 30 ml portions of ethyl acetate. The organic fractions were washed with water and brine, dried over anhydrous sodium sulfate, and concentrated to 1.9 g of product; MS (+) m/z 425.27 (M+1)
