Triphenylphosphine → HCID 54162185, compound

Participants

Reaction Steps

A solution of 2-methoxy-5-nitrophenol (5.58 g; 0.033 mol), (S)-1-methyl-2-hydroxymethylpyrrolidine (3.45 g; 0.03 mol) and triphenylphosphine (8.65 g; 0.033 mol) in dry THF (80 ml) was cooled to 50 and treated with DEAD (5.2 ml; 0.033 mol) over 15 min. The reaction mixture was allowed to stand at RT for 16 h, then evaporated in vacuo and partitioned 5% NaOH(aq)/Et2O. The organic phase was separated and extracted with 10% HCl(aq). The aqueous extract was washed with Et2O, basified with 40% NaOH(aq) and extracted with Et2O. The organic extracts were washed with H2O, dried over Na2SO4 and evaporated in vacuo to yield the title compound (D43) (6.79 g; 85%) MH+=267.
