実験手順
A solution of 1′-tert-butyl 7-methyl spiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′,7-dicarboxylate (1.8 g, 4.5 mmol) in HCl (4.5 mL, 4.0M in dioxanes, 18 mmol) was stirred at room temperature for 2 hours. The reaction mixture was evaporated to dryness to give methyl spiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-7-carboxylate hydrochloride (1.5 g, quant). ESI-MS m/z calc. 298.3. found 299.5 (M+1)+. Retention time: 1.06 minutes (3 min run).
