Procedure

A vial was charged with 6-bromo-4-fluoroisoquinolin-1(2H)-one (3.88 g, 16.03 mmol), Xantphos (0.464 g, 0.802 mmol), and Pd2(dba)3 (0.367 g, 0.401 mmol). The flask was flushed with Ar (g), then dioxane (32.1 ml), benzyl mercaptan (2.086 ml, 17.63 mmol), and n,n-diisopropylethylamine (5.60 ml, 32.1 mmol) were added in sequence. The reaction was heated to 110° C. and stirred for one hour. The reaction was diluted with water and stirred for 30 minutes. The solution was filtered and the solids were washed with water and dried under a nitrogen blanket overnight. The solids were triturated in ethyl acetate, stirred for two hours, and filtered. The solids were washed with ethyl acetate and vacuum dried to afford 6-(benzylthio)-4-fluoroisoquinolin-1(2H)-one as a yellow/green solid. (ESI) 286.2 (M+H)+.
