Versuchsvorschrift

To a solution of methyl 2-(2-methoxy-4-(spiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′-ylcarbonyl)phenoxy)acetate (140 mg, 0.303 mmol) in THF (4 mL) was added LiOH (600 μL of 2.0 M, 1.2 mmol) and the mixture was stirred at room temperature for 19 h. The mixture was filtered and was purified by HPLC using 5 mM HCl/water and MeOH to yield 2-(2-methoxy-4-(spiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′-ylcarbonyl)phenoxy)acetic acid. ESI-MS m/z calc. 448.2. found 449.3 (M+1)+; Retention time: 5.90 minutes (15 min run).
