Procedure

2 g of 2-(benzotriazole-2-yl)-4-(1,1,3,3-tetramethylbutyl)-6-(1-hexen-3-yl)-phenol and a trace of “Lindlar catalyst” (Fluka) in 25 ml of hexane was hydrogenated for 5 hours under normal hydrogen pressure. Then the reaction mixture was filtered and concentrated to yield 2 g of 2-(benzotriazole-2-yl)-4-(1,1,3,3-tetramethylbutyl)-6-(3-hexyl)-phenol as an orange liquid.
