The figure, in words

Drawn structure: a five-membered ring containing an N atom bearing H (top-left, drawn as H over N) and a second N atom (bottom-left), with a double bond drawn inside the ring on the right side and an unlabelled line stub (substituent) at the upper-right ring carbon. The lower-right ring carbon carries a CH2 line to an S atom, then a zigzag two-carbon chain to an N atom bearing H (H drawn below N). That N is bonded to a carbon that has a double bond to an N atom (drawn above) which carries a CN group, and a single bond to NHCH3.
