Abstract
Nitration of 1-phenylethyl acetate with NH4NO3-trifluoroacetic anhydride gave a mixture of ortho- and para-nitro products, which were separable by chromatography after saponification of the acetate. The ortho-isomer [1-(2-nitrophenyl)ethanol] was converted to the 1-(2-nitrophenyl)ethyl esters of monomethyl phosphate and of the γ-phosphate of ATP. The title isotopomers were prepared using either ammonium [15N]nitrate or [side-chain 1-13C]1-phenylethyl acetate as starting materials. A correction is made to the reported 1H NMR spectrum of caged ATP and the effects of isotopic substitution on the mass spectral fragmentation of 1-(2-nitrophenyl)ethanol are tabulated.
