Procedure
Tert-butoxycarbonyl-L-leucine monohydrate (8.92 g) and 1-benzylpiperazine (6.30 g) were condensed in the same manner as in the preparation of tert-butyl (s)-1-(4-diphenylmethylpiperazine-1-yl carbonyl)-3-methyl butylcarbamate to yield 8.06 g of tert-butyl (s)-1-(4-benzylpiperazine-1-yl carbonyl)-3-methylbutylcarbamate as a colorless amorphous substance (yield: 58%).
