Methacryloyl chloride → HCID 22964457, compound

Participants

Reaction Steps

To a solution of BDHN or 2(2,7-dihydroxynaphthyl) 2H-benzotriazole (5.0 g 18 m mol) and NaOH (0.8 g, 20 m mol) in water (100 ml) a solution of methacryloyl chloride (20 m mol, 4 ml) in chloroform (50 ml) was added dropwise with vigorous stirring. The mixture was stirred for 1 additional hour. The organic layer was separated and washed thoroughly with water before evaporation to yield a crude product that was recrystallized from carbon tetrachloride to give a yellow solid (2.5 g, 40% yield) of 2(2-hydroxy-7-methacryloxynaphthyl) 2H-benzotriazole--m.p. 167°-168° C.
