Anhydrous piperazine refluxed with methyl formate produced I-formylpiperazine (1725), which was reduced with lithium aluminum hydride to 1-methylpiperazine (1703). l-Nitroso-4-phenylpiperazine in tetrahydrofuran with diisopropylamine, methyllithium, and carbon dioxide formed 2-carboxy-l-nitroso-4-phenylpiperazine, which was cleaved by dry hydrogen chloride in benzene to 3-carboxy-l-phenyl-piperazine (1726). Distillation of the calcium salt of rra/is-2,3-dicarboxy-l, 4-di-phenylpiperazine gave 1,4-diphenylpiperazine (1669). Reduction of 1-ethoxy-carbonyl-4-trifluoroacetylpiperazine with borane in tetrahydrofuran formed...
