Procedure

3-chloro-1,2,4-benzotriazine 1-oxide was treated with a slight excess of tri-N-butylvinyltin in a mixture of acetonitrile, tritoluyl phosgene and triethylamine, using palladium II catalysis (Pd II acetate) in a sealed tube at 100° C. for 48 hours. Removal of solvent and purification by column chromatography gave 3-vinyl-1,2,4-benzotriazine 1-oxide (33). Reduction with 9-borabicyclo [3.3.1]nonane (9-BBN) followed by oxidation with sodium hydroxide and hydrogen peroxide gave the title compound 3-(1-hydroxyethyl)-1,2,4-benzotriazine 1-oxide (34).
