Reaction Steps

K2CO3 (0.085 mol) was added to a mixture of 3-aminothiophenol (0.075 mol) in DMA (150 mL), then 4-chloro-2-dimethoxymethyl-1-nitrobenzene (0.050 mol) was added and the reaction mixture was stirred for 2 hours at 80° C. H2O was added and the mixture was extracted with diisopropyl ether. The crude product was purified by column chromatography (eluent: 70:30 CH2Cl2:hexane up to 99:1 CH2Cl2:CH3OH). The product fractions were collected and the solvent was evaporated to yield the title compound as a residue which contained about 10% of an impurity. (The product was used in subsequent steps without further purification.)
