Procedure
7-Chloro-1′-(3-methoxy-4-(trifluoromethyl)benzoyl)spiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1-carbaldehyde (50 mg, 0.10 mmol) dissolved in dry THF (3 mL) was cooled to 0° C. NaBH4 (3.9 mg, 0.10 mmol) was added and stirring was continued for 30 min. The mixture was filtered through Celite, evaporated and purified by column chromatography (5-30% AcOEt in dichloromethane) to yield (7-chloro-1-(hydroxymethyl)spiro[benzo[b]pyrrolo[1,2-d][1,4]oxazine-4,4′-piperidine]-1′-yl)(3-methoxy-4-(trifluoromethyl)phenyl)methanone. ESI-MS m/z calc. 506.9. found 507.0 (M+1)+; Retention time: 1.96 minutes (3 min run).
