5-Amino-pyrazole-4-carbaldehyde

Similar conditions were used to condense pyrazol-3-one 30 with 5-[4 -(5-formylfuran-2-yl)biphenyl-4-yl]furan-2-carbaldehydes 175a c to give ( /Z)-4- [5-(4 -substituted biphenyl-4-yl)furan-2-ylmethylene]-amino pyrazol-3-ones 176a-c in 45%, 52% and 20% yields, respectively (92JOU431) (Scheme 46). [Pg.59]
