Reaction Steps

To a solution of 1-(cyclopropylmethyl)-5-{4-[(3-methyl-2,4-dioxoimidazolidin-1-yl)methyl]phenyl}-1H-benzotriazole-4-carbaldehyde (Example 20, 72 mg, 0.18 mmol) in methanol (1.8 mL) was added sodium borohydride (6.8 mg, 0.18 mmol). After 1.5 hours, the mixture was treated with water, diluted with dichloromethane and washed with brine. The organic extract was dried with magnesium sulfate, filtered and concentrated in vacuo. The residue was purified via silica gel chromatography (ethyl acetate/hexane gradient), providing the titled compound: 1H NMR (400 MHz, CDCl3) 7.54 (d, 1H, J=8.8 Hz), 7.42-7.45 (m, 3H), 7.35 (d, 2H, J=8.0 Hz), 5.12 (d, 2H, J=6.4 Hz), 4.65 (s, 2H), 4.55 (d, 2H, J=7.2 Hz), 3.83 (s, 2H), 3.08 (s, 3H), 1.40-1.47 (m, 1H), 0.67-0.71 (m, 2H), 0.51-0.55 (m, 2H) ppm. LRMS m/z (M+H) 406.0 found, 406.2 required.
