The Synthesis and Molecular Structure of 2-(4-Methoxybenzyl)-4-nitro-2H-indazole

Two novel indazole derivatives protected with p-methoxybenzyl group were synthesized and characterized. The crystal and molecular structure of 2-(4-methoxybenzyl)-4-nitro-2 H-indazole as one out of the two regioisomers is reported. The compound was obtained from a saturated petroleum ether/ethyl acetate mixture and crystallizes in the triclinic space group P`1. The unit cell parameters are: a = 6.8994(1) ？, b = 9.8052(2) ？, c = 11.1525(2) ？; α = 71.729(1)°, β = 79.436(1)°, γ = 74.349(1)° and V = 685.83(2) ？ 3. There are two independent molecules found in the asymmetric unit.
