Resolution of MNR26-7 with (-)-dibenzoyl-L-tartaric acid (MNR6-1) to obtain MNR27-26

Starting material from
Hydrolysis of MNR11-18 to give MNR26-7
Synthesis of (-)-Dibenzoyl-L-tartaric acid (MNR6-1)


Hazard and Risk Assessment:
As for MNR2-1

MNR26-7 (0.030 g, 0.11 mmol) and (-)-dibenzoyl-L-tartaric acid. 2IPA (0.05 g, 0.11 mmol) was dissolved in a isopropanol (2.5 mL).

MNR27-27 - nothing else added
MNR27-28 - water (0.5 mL) sdded
MNR27-29 - water (0.25 mL) added

The reagents went into solution with minimal heating and we left to stand, sealed, at room temperature overnight.
