실험 절차

A suspension of 1-(6-(2-cyanoacetyl)-2-benzothiazolyl)-3-ethylurea (0.56 g, 1.94 mmol) and platinum (IV) oxide (0.176 g, 0.78 mmol, 0.40 eq) in 50 mL of 2/3 mixture of MeOH and chloroform was purged and bubbled with hydrogen gas. It was stirred under hydrogen gas for about 2 days. The mixture was filtered and concentrated to give 0.689 g (quantitative yield) desired compound. LC/MS 292.9 (M+1); LC retention time 1.80 min. HPLC purification gave corresponding acetic acid salt. LC/MS 292.9 (M+1); LC retention time 1.80 min. In a similar reaction, compound as an acetate salt form was obtained after HPLC purification.
