실험 절차

To a stirred solution of N-[(5-bromo-1-naphthalenyl)carbonyl]-N-methylglycine methyl ester (35.5 g, 106 mmoles, described in Example 2) in dry pyridine (100 ml), phosphorus pentasulfide (44.5 g, 200 mmoles) was added portionwise. The mixture was stirred and refluxed for 1.5 hr and then poured into a liter of water at 50° to 80° C. (caution: evolution of copious quantities of H2S). The mixture was allowed to cool to 20° to 22° C. (room temperature), filtered and the filtrate was extracted with ethyl acetate. The extract was washed with 1N aqueous HCl solution, brine, a saturated solution of sodium carbonate and brine, dried (MgSO4), filtered and evaporated to dryness. The residue was recrystallized from ethanol-water (4:1) to give the title compound; mp 85°-86° C.; NMR (CDCl3) δ 3.0 (s, 3H), 3.85 (s, 3H), 4.58 & 5.37 (2d, J=17, 2H), 7.1-8.3 (m, 6H); UV λmax (EtOH) 281 nm (ε 14,480), 218 (14,480).
