Reaction Steps
To a suspension of potassium thiocyanate (KNCS) (611 mg, 6.29 mmol) in dichloromethane (30 mL) was added 200 μL of PEG-400 followed by 4-chlorobenzoyl chloride (1.00 g, 5.71 mmol). The suspension was heated to 40° C. for 2 h, then cooled to room temperature and filtered into an addition funnel. The solution was added dropwise into an ice cold solution of t-butylamine (418 mg, 5.71 mmol) in dichloromethane (30 mL). The reaction was stirred for 20 minutes following the complete addition, and then it was concentrated in vacuo delivering N-(tert-butylcarbamothioyl)-4-chlorobenzamide as a yellow solid (1.49 g, 96% yield). 1HNMR (400 MHz, DMSO-d6) δ 11.11 (s, 1H), 11.02 (s, 1H), 7.87 (d, 2H, J=8.8 Hz), 7.54 (d, 2H, J=8.4 Hz), 1.51 (s, 9H).
