실험 절차

Isoamyl nitrite (22.0 mmol) is added to a solution of 2-amino-benzothiazole-7-carboxylic acid methyl ester (10.1 mmol) in THF (29 mL). The mixture is heated to reflux for 4 h, the solvents are removed in vacuo and the residue is purified by FC (gradient: heptane to EtOAc/heptane 4/6) to give the desired product.
