Participants

Reaction Steps

To a round-bottomed flask equipped with magnetic stirring was added Example 27, (2E)-3-[4-(tert-butyl)phenyl]-N-{3-[2-(1,3-dioxobenzo[c]azolin-2yl)ethoxy]phenyl}prop-2-enamide, (856 mg, 1.83 mmol), EtOH (15 mL) and hydrazine (574 uL, 18.3 mmol, Aldrich). The reaction mixture was stirred at 25° C. for 2 h. The mixture was concentrated in vacuo, the residue dissolved in EtOAc (40 mL), washed with 10% K2CO3 (15 mL), water (15 mL), dried over Na2SO4, filtered and concentrated in vacuo. Purification by silica gel chromatography (step gradient, EtOAc followed by 1:1 EtOAc:EtOH) provided the title product as an oil. MS (ESI, pos. ion) m/z: 339 (M+1).
