Reaction Steps

1,1′-Thiocarbonyldiimidazole (4.51 g, 25.3 mmol) was added to a solution of N-phenylethylenediamine (3 mL, 23.02 mmol) in THF (230 mL) and the mixture was stirred for 2 h at room temperature. DCM was added and the solution was washed with 1N HCl, dried over anhydrous sodium sulfate and concentrated under reduced pressure affording title compound 301 (1.45 g, 8.13 mmol, 35.3% yield). m/z: 179.1 (M+H)+
