Abstract
The synthesis and structure of the title compound, C21H17FN4O3S, is describ ed. It is a novel spiro-indole in which the sp(3) spiro-C atom is linked to S and N atoms. The pyrazole ring is aligned at 76.8(1)degrees with respect to the attached phenyl ring and at 87.7(1)degrees with respect to the best plane through the spiro ring. Molecules are linked to form infinite chains by N-H ... O hydrogen bonds, with N ... O = 2.7002(15) Angstrom.
