Reaction Steps

To a solution of 1-(2,3-diaminophenoxy)-3-[[2-[4-[[[3-(4-methylphenyl)-1,2,4-oxadiazol-5-yl]methyl]thio]phenyl]ethyl]amino]-2-propanol (0.077 g, 0.172 mmol.) in acetic acid (1.2 mL) at 5° C. was added a solution of sodium nitrite (0.013 g, 0.189 mmol) in water (0.5 mL). The mixture was stirred for 30 minutes and evaporated to dryness. The residue was purified by flash chromatography (silica gel; CH2Cl2/MeOH (3/1) to afford 0.079 g of the pure title compound. MP=110° C.
