Phenyl isocyanate → (S)-(6-cyano-1,2,3,4-tetrahydroquinolin-3-yl)-3-phenylurea

Participants

Reaction Steps

To a solution of (S)-3-amino-1,2,3,4-tetrahydroquinoline-6-carbonitrile (52 mg, 0.3 mmol), prepared as described in Example 1F, in CH2Cl2 (2 mL) at RT was added phenyl isocyanate (33 μl, 0.3 mmol) dropwise. After addition, the reaction was stirred at RT for 1 h. The product was collected by filtration and washed with CH2Cl2-hexanes (1:1) to give the title compound (85 mg, 97%) as a white solid.
