A solution of 116 (0.27 g) in MeOH (10 mL) was treated with go 0.135 M sodium methoxide (4.9 mL) in MeOH. After 4 h, the solvent was evaporated, the residue was suspended in H2O and the solid was collected by filtration. The solid was crystallized from EtOAc-ether to give a tan powder, m.p. 206-208° C.
