Following discussion (Issue #232) a selection of target compounds for the second round of biological evaluation for the triazolopyrazines.

This compound is a representative example from the chiral ethers that could be resolved by preparative HPLC at a later stage in the project. It also meets 3 of the 4 ESAC criteria:

Aim for log P between 1.5 and 3.5 (well CLogP...need to clarify)
Revisit other cores with good metabolic profiles, e.g. MMV669846
Use more sp3 carbons, and de-planarize through chirality at C-5 or in substitutions at C-2 or C-5

Currently closing para nitrile compounds as para-difluoromethoxy compounds were preferentially targeted ( We may revisit these compounds in relation to #304 but currently prioritising compounds here #358.
