Reaction Steps

To the stirred mixture of (2S)-2-amino-4-[2-(1,3,4,5-tetrahydro-2H-2-benzazepin-2-yl)quinolin-4-yl]butan-1-ol (110 mg, 0.3 mmol), potassium acetate (90 mg, 0.91 mmol), methanol (8 mL) and water (2 mL) was added a solution of cyanogen bromide (32.3 mg, 0.3 mmol) in cold methanol (2 mL) at 0° C. After the addition, the resulting mixture was stirred at room temperature for 24 hours. The solvent was removed under reduced pressure to give a residue which was purified by preparative HPLC to give 40 mg of product as a white solid (yield was 34.5%). MS obsd.
