Procedure
To a solution of (36) (80 mg, 0.346 mmol) stirring in CH2Cl2 (2 mL), under a nitrogen atmosphere, was added pyridinium chlorochromate (150 mg, 0.694 mmol). The reaction mixture was allowed to stir overnight then filtered through a plug of silica gel. The crude aldehyde was carried on to the following step.
