Procedure
75B (660 mg, 2.75 mmol) was suspended in EtOH (2 mL) and aqueous NaOH (1 M, 6 mL) and was heated to 80° C. for thirty minutes. Upon cooling to room temperature, the solution was acidified with HCl (concentrated), was cooled to 0° C., and was filtered. The white crystalline precipitate was dried under vacuum (356 mg, 57%). NMR 1H (ppm, CDCl3): 7.96-7.91 (m, 2H), 7.40-7.36 (m, 2H), 7.30-7.15 (n, 5H), 3.02-2.90 (m, 4H).
