반응 단계
A solution containing 2.1 g (0.0157 mol) of rhodanine, 2.76 g (0.0151 mol) of 3,4-dihydroxy-5-nitrobenzaldehyde and 0.15 ml of piperidine in 10 ml of acetic acid was heated for 7-8 h at 100° C. After cooling the crystalis were filtered and washed with 2-propanol. Yield 4.0 g (89%), mp>350° C. (decomp.).
