Procedure

To a solution of the methyl ester of Step 2 (400 mg; 1.3 mmol) in THF (8 mL) and water (6.63 mL) was added LiOH (1 N; 1.37 mL). The reaction mixture was stirred for 30 minutes and then acidified with 1.0 N HCl to pH=3≈4. The mixture was extracted with EtOAc (20 mL, twice). The combined organic layer was washed with water, brine, and then concentrated in vacuo to afford the title compound (370 mg). (M+1) 294.
