TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Condensation of carboxylic acid compound of formula (I) is carried out with solid phase resin or solid phase compound by n3-1 times , followed elimination of protecting group (X) of obtained solid phase joined compound to obtain solid phase joined compound of formula (i). Then n2 times condensation of solid-phase joined compound (i) and carboxylic acid compound of formula (II) is performed to obtain solid phase joined compound (ii), and n-time condensation of solid-phase joined compound (ii) and carboxylic acid compound of formula (III) is performed to obtain solid phase joined compound of formula (iii). Condensation reaction of solid phase joined compound (iii), with 1-10 times of carboxylic acid compound of formula (IV) or 1-100 times of carboxylic acid compound of formula (IV) is performed, to obtain solid phase joined compound of formula (iv). Then protecting groups (Za 2-Za 4, and X) are eliminated and photosensitive group is bonded with a nitrogen atom in which the protecting groups are bonded. Then solid phase resin or solid phase compound are separated from the obtained compound (the protecting group is not eliminated at the time of bonding a hydroxyl or amino group with carbon atom in which the solid phase resin or solid phase compound is boned). The hydrogen atom is bonded with a nitrogen atom in which the protecting groups are bonded, to obtain compound (1).n1-n3,X,m1-m10,E 1,X=same as defined above;A=solid phase such as solid-phase resin or a solid-phase compound; andZa 1-Za 4=different protecting group in X. Preferred Definitions:    m7=1 or 2, or 0-2;    m8=1 or 0;    m9=0-11;    m10=1-3 or 0-2;    E 2=N or CH 2;    n1,n3=0-5, preferably 0-2;and    n2=1-20, preferably 1-10    EXAMPLE - A prepared compound of formula (18) (A=(5-(4'-amino methyl-3',5'-dimethoyx phenoxy) valeric acid) resin) was processed at room temperature in trifluoroacetic acid (TFA) solution of 5% meta-cresol (0.3 ml) for 1.5 hours, and TFA solution was collected by filtration. The remaining solid phase resin was washed by TFA (0.2 ml). The filtrate was dropped to cold diethyl ether (10 ml) and deposit was collected by centrifugation. The remaining solid was dissolved in methanol after adding diethyl ether and precipitating, centrifugation was performed for 3 times. Remaining ether was removed and compound of formula (19) (E=group of formula (E), J=group of formula (J), Q=group of formula (Q)) (0.6 mg) was obtained after drying.
