Trimethylsilyl isocyanate → HCID 86612267, compound

Participants

Reaction Steps

Trimethylsilyl isocyanate (1.62 mL, 12.0 mmol) and 1,8-diazabicyclo[5.4.0]undec-7ene (one drop) were added to a solution of 1-[4-(methoxyamino)butyl]-2-methyl-1H-imidazo[4,5-c]quinolin-4-amine (3.00 g, 10.0 mmol) in dichloromethane (100 mL). The reaction mixture was stirred overnight at room temperature, then concentrated under reduced pressure to afford 4.1 g of crude N-[4-(4-amino-2-methyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]-N-methoxy-N′-(trimethylsilyl)urea, which was used without purification in the next step.
