To a solution of 3-{[tert-butyl(dimethyl)silyl]oxy}-5-[(1E)-3-methoxyprop-1-en-1-yl]benzaldehyde from Amine 36, Step 3 (1 eq.) in EtOAc (0.1 M) was added palladium (10% w/w over activated carbon, 10% loading). The vessel was evacuated and back filled with hydrogen. The reaction suspension was then stirred under a balloon atmosphere of hydrogen for 1 h. The reaction was quenched with dichloromethane and filtered through a bed of celite. The insolubles were washed further with EtOAc and methanol. Concentration of the filtrate in vacuo and purification of the crude product thus obtained by way of column chromatography (SiO2, Hex→3:2 (v/v) Hex:EtOAc) afforded the title compound as a pale yellow oil.
