1. Start with a pyrazole ring, a five-member aromatic ring containing two adjacent nitrogens (one bearing an NH).
2. Label the ring so that the NH-bearing nitrogen is N-1, the other nitrogen is N-2, and the three ring carbons are C-3, C-4, and C-5.
3. At C-3, attach a single substituent consisting of a saturated pyrrolidine ring. This pyrrolidine is connected through a chiral carbon center with S configuration, located at the meta position relative to the pyrrolidine's nitrogen. The pyrrolidine's nitrogen in turn is substituted with a 3,3-dimethylpropanoyl group (i.e., a carbonyl attached to an isobutyl chain, -C(=O)-C-C(CH3)2).
4. At C-5, there is a -CH2-O-phenyl substituent whose phenyl ring bears one chlorine substituent at the meta position relative to the point of attachment.
