Reaction Steps

To a THF (0.12 M) solution of N-{2-[3,4-dichloro-5-({[(1,1-dimethylethyl)(dimethyl)silyl]oxy}methyl)phenyl]ethyl}propanamide (1 eq.) from the previous step was added TBAF (1.0 M THF solution, 1.1 eq.). The resulting solution was stirred at RT for 2 h. The now orange solution was diluted with ether and quenched with 1 N aq. NaOH. The aqueous layer was separated and back-extracted with ether. The combined organic extracts were washed further with water and brine, dried over Na2SO4 and filtered. Concentration of the filtrate in vacuo afforded the crude title compound as a pale yellow oil.
