実験手順
In like manner to the reduction of diethyl 2-methyl-2-(3-nitrophenoxy)malonate, methyl 3-methoxy-4-[(6-nitroindazol-1-yl)methyl]benzoate was reduced to provide methyl 4-[(6-aminoindazol-1-yl)methyl]benzoate. 1H NMR (CDCl3): δ 7.88 (s, 1H), 7.53 (d, 1H, J=8.8 Hz), 7.51 (d, 1H, J=8.8 Hz), 7.50 (d, 1H, J=1.7 Hz), 6.67 (d, 1H, J=8.8 Hz), 6.56 (dd, 1H, J=1.7 and 8.8 Hz), 6.45 (d, 1H, J=1.2 Hz), 5.50 (s, 2H), 3.94 (s, 3H), 3.87 (s, 3H), 3.79 (br s, 2H).
