A process for making an N1-(2′-pyridyl)-1,2-alkanediamine sulfamic acid of formula II by reacting a compound of formula I with NH
2
R′
1
wherein R and R′ are as defined in the specification. The invention also includes the compound of formula II, and optical isomers thereof. The compound of formula II is an intermediate useful for making chiral piperazine derivatives which are active at the 5-HT
1A
receptor.
Novel piperazine derivatives are provided having the formula
1
wherein R
1
is cyano, nitro, trifluoromethyl or halogen, or pharmaceutically acceptable acid addition salts thereof, which are useful as 5-HT
1A
receptor antagonists.

A process for formation of N-aryl piperazines with chiral N′-1-[benzoyl(2-pyridyl)amino]-2-propane side-chains having the structure shown in formula below, and for making intermediate compounds therefor.
In this process, chirality is introduced at the piperazine ring formation step and 2-aminopyridyl substitution is incorporated via displacement. The resulting N,N′ disubstituted piperazines act on the central nervous system at 5HT receptors.
