The known aminoacid (I) is esterified to (II) employing methanolic H2SO4. Ester group reduction in (II) with LiAlH4 yields alcohol (III). The O-benzyl group of (III) is then removed by catalytic hydrogenation in the presence of Raney nickel, providing phenol (V). Alternatively, compound (III) is converted into diol (V) by O-benzyl group hydrogenolysis, followed by LiAlH4 reduction of the resultant ester (IV). Finally, selective monoesterification of diol (V) with isobutyryl chloride (VI) and triethylamine gives rise to the title compound.
