Reaction Steps

To an ice cold solution of tert-butyl (((tert-butoxycarbonyl)amino)(1H-pyrazol-1-yl)methylene)carbamate (500 mg, 1.611 mmol), tert-butyl(3-hydroxypropyl)carbamate (282 mg, 1.611 mmol) and triphenylphosphine (634 mg, 2.417 mmol) dissolved in THF (16 mL) was added DIAD (470 μl, 2.417 mmol) and stirred for 16 h. The reaction mixture was concentrated in vacuo and the crude residue was purified via silica gel chromatography (EtOAc-Heptane) to afford the title compound (600 mg, 80%). LCMS: Rt=1.02 min, m/z=468.4 (M+1) Method 2m_acidic.
