실험 절차

Ethyl 2-hydroxy-5-aminobenzoate (31.8 g, 0.176 mole) was mixed with benzaldehyde (17.8 ml, 0.176 mole), and the mixture was heated to 100° C. for 10 minutes and subsequently cooled with ice-water. The resulting oil was recrystallized from 96% ethanol, with activated carbon, to give the title compound (31.6 g, 67%), m.p. 63°-65° C. Found (Calc. for C16H15NO3) C 71.18 (71.38), H 5.63 (5.58), N 5.22 (5.20).
