Participants

Reaction Steps

2-(3-Phenylpropyl)-6-[2-(N-hydroxyamino)-ethoxy]-1-oxo-1,2,3,4-tetrahydroisoquinoline (498 mg, 1.5 mmol) is dissolved in dioxane t 15 mL) and methyl isocyanate (0.22 mL, 3.7 mmol) is added. After 12 hours, the reaction mixture is diluted with EtOAc (150 mL) and the organic phase washed with 2N HCl (2×200 mL), H2O (4×200 mL), saturated NaHCO3 solution (2×200 mL), saturated NaCl solution (2×200 mL), dried over MgSO4 and concentrated in vacuo. The resulting material is triturated with hexanes and recrystallized from CH2C2 /hexanes to give 2-(3-phenylpropyl)-6-{2-[N-(methylaminocarbonyl)-N-hydroxyamino]-ethoxy}-1-oxo-1,2,3,4-tetrahydroisoquinoline, m.p. 138°-139°.
