Procedure

To a mixture of EXAMPLE 402C (1.03 g), naphthalen-1-ol (519 mg), and triphenylphosphine (905 mg) in tetrahydrofuran (15 ml) at −10° C. was added di-tert-butyl azodicarboxylate (794 mg) slowly. After one hour, the reaction was allowed to warm to room temperature. Stirring was continued for two hours at room temperature. The reaction mixture was concentrated. The concentrate was purified by column chromatography on silica gel with 0-4% ethyl acetate in hexanes.
