Reaction Steps

A mixture of a solution of the product of step (b) (34.6 g) in ethyl acetate (600 ml) and 10% palladium/carbon (3 g) was stirred under an atmosphere of hydrogen for 5 hours at ambient temperature. The mixture was filtered through a pad of kieselguhr and the solvent was removed by evaporation to give a solid residue which was crystallised from ethyl acetate/hexane to give 3,4-di-t-butoxycarbonylmethoxybenzoic acid; m.p. 118°-120° C.; NMR Spectrum (d6 -DMSO) 1.41 (s, 18H), 4.7 (s, 2H), 4.76 (s, 2H), 6.95 (d, 1H), 7.39 (m, 1H), 7.55 (dd, 1H); Microanalysis found: C, 59.5; H, 6.8%; C19H26O8 requires C, 59.7; H, 6.9%.
