Reaction Conditions:

with water;lithium hydroxide in tetrahydrofuran;methanol;water at 20; for 18 h;

Steps:

At 4°C, LiOH H₂0 (6.36 g, 152 mmol) was added to a soln of 27 (28.82 g, 75.8 mmol) in MeOH (86 mL), H₂0 (85 mL) and THF (270 mL). The mixture was stirred for 18 h at rt, acidified with 1 M aq. HCI soln (500 mL) and extracted with EtOAc. The organic phase was dried (Na₂S0₄), filtered and concentrated to give 123 (26.5 g, 99%).
