Hydrazide fixed to a resin represented by the following formula:
P-Q-CO-NH-NH2 (I)
where P represents a main chain of a resin polymer and Q represents a hydrocarbon side chain optionally having a substituent which may be boned via a heteroatom, and a hydrazone derived therefrom and fixed to a resin
P-Q-CO-NH-N=CH-R1 (II)
are provided, and solid phase synthesis of pyrazolone is conducted using the same, thereby enabling synthesis of pyrazolones by the application of the Mannich type reaction based on the solid phase synthesis and efficient construction of libraries for various kinds of them.
