Reaction Steps
To a solution of 4-methoxybenzyl 5-(N-CBz-L-valyloxy)-4-stearoyloxy-2,2-dimethylvalerate (25.5 g, 33 mmol) in CH2Cl2 (400 mL) at room temperature, was added trifluoroacetic acid (40 mL). After 1 h at room temperature, the reaction mixture was concentrated under reduced pressure. The crude product was column chromatographed (silica gel, 3→5% MeOH in CH2Cl2), to give 19.8 g of 5-(N-CBz-L-valyloxy)-4-stearoyloxy-2,2-dimethylvaleric acid.
