Vartanyan, R. S.,Gyul'budagyan, A. L.,Vartanyan, S. A.
, p. 370 - 372 (2007/10/02)
The reaction of 5-amino-1,3-diphenylpyrazole with benzaldehyde gives 5-benzylideneamino-1,3-diphenylpyrazole, wich then undergoes cyclization with mercaptoacetic acid to give 1,3,4-triphenyl-1H-pyrazolothiazepin-7-one.
