Reaction Steps

To a solution of the product of Step B (0.5 g) in methanol (6 mL) was added Pd-C(10%)(0.05g), and the reaction mixture was stirred at room temperature for 6 h under an atmosphere of hydrogen gas. The catalyst was filtered off and the filtrate was concentrated in vacuo to give the desired methyl α-(4-amino-2-n-propylphenoxy)-2-(3,4-methylenedioxyphenyl)acetate (0.5 g) as a solid. This material without further purification was dissolved in dry THF (5 mL) and reacted with N-iso-propylisocyanate (0.1 mL) at room temperature for 12 h. Purification of the crude product by flash chromatography using EtOAc-hexanes (1:2) gave the titled compound as white solid (0.36 g).
