Abstract:
Disclosed is a method capable of selectively synthesizing cationic lipids by controlling the introduction rate of a fatty acid group with respect to an oligoalkyleneamine by the change of reaction conditions.

Claim (Index 5):
A method for preparing a cationic lipid of Formula 1 of  claim 1  where R1 and R4 are saturated or unsaturated fatty acid group having 12 to 26 carbon atoms, and one of R2 and R3 is hydrogen, wherein the method comprises\n reacting the cationic lipid of Formula 1 defined in  claim 1  where R1 and R4 are saturated or unsaturated fatty acid group having 12 to 26 carbon atoms and R2 and R3 are hydrogen, with a fatty acid alkyl ester of Formula 3 defined in  claim 1  to prepare the cationic lipid of Formula 1 where R1 and R4 are saturated or unsaturated fatty acid group having 12 to 26 carbon atoms and one of R2 and R3 is hydrogen.
