Reaction Steps

Into a solution of (RS)-3-[(6-triphenylmethylazo-3-pyridazinyl)oxy]-1,2-propanediol (5.45 g) in 95% ethanol (100 ml) and tetrahydrofuran (50 ml) containing 5% palladium on charcoal (1.1 g) hydrogen was bubbled, at room temperature, for 16 hours. Removal of the catalyst and evaporation of the solvent gave a residue which was crystallized from 2-propanol to yield 3.2 g of the title compound, m.p. 174°-176° C. Mass spectrum (E.I. 70 eV, 1.5 mA), m/z=412 (M-N2H2)+, 338 (M-C3H8N2O2)+, 243 (Ph3C)+.
