Derivatives of such L-proline compounds are useful for the treatment or prophylaxis of diabetes, obesity, HIV infection, cancer metastasis and like are disclosed in U.S. Patent No. 7,074,794. The side chain moiety introduced at y-position is substituted piperazine derivatives. U. S. Patent No. 7,807,671 disclosed some compounds useful for the treatment of HIV and AIDS which have this side chain piperazine derivative moiety.
Such side chain piperazine derivative moiety was prepared by two methods which were disclosed in U. S. Patent No. 7,807,671 wherein method 1 teaches addition of piperazine to the solution of XpY-Z in THF, dioxane or DMF at RT or 115°C for 17 hours.
In method 2 the solution of piperazine in dry THF was added to n-BuLi at RT. After that Xi-Y-Z was added to the solution and stirred for I to 10 hours at RT to 115°C wherein A is H or Li.
U. S. patent application No. 2013/0310396 disclosed the reaction of XrY-Z with piperazine in DMF, while stirring K2CO3 and Pd(OAc)2 were added and heated to 110°C for 12 hours and solid was filtered.
PCT application No. 2014/041560 disclosed specific example to produce such piperazine derivative. That example is generically represented as below in which compound of formula NH2-Y-Z with bis (2-chloroethyl) N-protected derivative compound to obtain piperazine derivative.
