Versuchsvorschrift

NaOH (aq, 2 M, 0.7 mL) was added to a stirred solution of ester 23a (53.1 mg, 0.14 mmol) in pyridine (0.7 mL) at room temperature. After 3 h, the reaction was diluted with DCM and washed with HCl (3×, 1 M in brine), NaHCO3 (aq, sat), brine and dried over Na2SO4 before being purified by preparative HPLC to give acid 23b in 70% yield (35 mg).
