実験手順

To 3.0 g of N-[3-(3-methyl-1,2,4-triazolo[4,3-b]pyridazin-6-yl)phenyl]acetamide in 250 ml of dimethylformamide under argon, was added 0.6 g of sodium hydride (50% in oil). This mixture was stirred for 1 hour, then 1.07 ml of allyl bromide was added. The mixture was stirred overnight, then poured into 200 ml of water and extracted with 150 ml portions of dichloromethane. The extracts were combined, dried and evaporated in vacuo. The residue was chromatographed as described in Example 1. The active fractions were combined, evaporated and the solid recrystallized from ethyl acetate-hexane, giving 1.46 g of the desired product as tan crystals, mp 114°-115° C.
