반응 단계
O-phenylenediamine (1.0 g., 0.0092 mol.) was dissolved in tetrahydrofuran (50 ml.) and 3-bromopyruvic acid (1.7 g., 0.0102 mol.) added. The reaction mixture was stirred at room temperature for one hour, during which time the product precipitated as a yellow solid. The product was collected by filtration and crystallized from methylene chloride. (0.91 g., m.p. 221°-223° (dec.) 41%)
