From p-t-butylcalix[4]arene bis(diethylphosphate) ester(1), monodehydroxymonoamino-p-t-butylcalix[4]arene (3) and diamino-p-t-butyl-calix[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.
