Reaction Scheme 6 illustratively shows the preparation of N-(12-methoxy-1-oxododecyl)-D-alanine, ethyl ester wherein N-(t-butyloxycarbonyl)-D-alanine (16) is treated with tetramethylammonium hydroxide pentahydrate in acetonitrile followed by the addition of ethyl iodide to form N-(t-butyloxycarbonyl)-D-alanine, ethyl ester (17) which in turn reacts with trifluoroacetic acid in methylene chloride to give the trifluoroacetate salt of D-alanine ethyl ester (18) which, when treated with 2-methoxydodecanoyl chloride (9) in methylene chloride, gives the desired fatty acid amino ester (19).
