Step III: Preparation of Fmoc-(2S,4R)-(4-O-CO-NH-CH2-CH2-NH-Boc)-Pro-OH. the methyl ester obtained in step II was converted to free acid by hydrolysis reaction. This is done by adding 1N sodium hydroxide solution to a mixed solvent of 1,4-dioxane and water for the reaction. This step produced a mixture of H-(2S,4R)-(4-O-CO-NH-CH2-CH2-NH-Boc)-Pro-OH with the target product Fmoc-(2S,4R)-(4-O-CO-NH-CH2-CH2-NH-Boc)-Pro-OH. The reaction yield was 55%.

Yield: 55%
Reaction Conditions:
with water;sodium hydroxide in 1,4-dioxane
Steps:
3.3 Step-III: Preparation of Fmoc-(2S,4R) -(4-0-CO-NH-CH2-CH2-NH-Boc)-Pro-OH
Step-III: Preparation of Fmoc-(2S,4R) -(4-0-CO-NH-CH2-CH2-NH-Boc)-Pro-OH The methyl ester obtained in step-II was then hydrolyzed to free acid by treatment with IN sodium hydroxide in a mixture of 1, 4-dioxane and water. Providing a mixture of H- (2S,4R) -(40CO-NH-CH2-CH2-NH-Boc)-Pro-OH and the desired product Fmoc- (2S ,4R) -(40CO-NH-CH2-CH2-NH-Boc)-Pro-OH. Yield: 55%
