Reaction Steps

(R)-(8-Chlorospiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′-yl)(4-((2,2-dimethyl-1,3-dioxolan-4-yl)methoxy)-3-methoxyphenyl)methanone (41 mg, 0.076 mmol) and 4-methylbenzenesulfonic acid hydrate (2.9 mg, 0.015 mmol) were dissolved in MeOH (760 μL) and H2O (76 μL) was added. The reaction mixture was heated at 80° C. for 45 min. The mixture was filtered and the residue was purified by reverse phase HPLC using 5 mM HCl/H2O and MeOH to yield (S)-(8-chlorospiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′-yl)(4-(2,3-dihydroxypropoxy)-3-methoxyphenyl)methanone. ESI-MS m/z calc. 498.2. found 499.3 (M+1)+; Retention time: 4.72 minutes (15 min run).
