Participants

Reaction Steps

To a stirred mixture of T23.1 (0.460 g, 2 mmol) in MeOH (8 mL) was added PPTS (0.04 g, 0.2 mmol). The reaction mixture was then stirred for 24 hours and then concentrated in vacuo. The residue was purified on silica gel (0-20% EtOAc in hexanes) to yield T23.2 as a colorless oil (0.320 g, 98% yield).
