From p-t-butylcalix[4]arene bis(diethylphosphate) ester(1), monodehydroxymonoamino-p-t-butylcalix[4]arene(3) and diamino-p-t-butylcalix[4]arene(4) were synthesized in liquid ammonia-co-solvent in the presence of KNH2. This is the first successful example for the substitution of the OH group with the NH2 group.
