Yield:271-44-3 73%
Reaction Conditions:
with hydrazine hydrate;sodium t-butanolate;[Pd(cinnamyl)Cl]2;C27H38NP in toluene at 65; for 1.5 h;
Steps:
8
[0251] In Example 8, 1-H-indazoles were prepared directly from 2-chlorobenzaldehydes and hydrazine. The protocol above allows for the generation of substituted NH-indazoles with moderate to good yields in short reaction times (1 - 1.5 h) and under relatively mild conditions (65 - 90 °C
