Procedure

A mixture of 109 (10 mg, crude, 0.03 mmol for aldehyde) (made from compound 108 as in the preparation for 110) and 2,5-diaza-bicyclo[2.2.1]heptane hydrobromide (10 mg, 0.056 mmol) in 5% acetic acid solution in DCE (1 mL) was stirred at rt for 20 min. Sodium cyanoborohydride (20 mg, 0.32 mmol) was added and the reaction mixture was stirred at rt overnight. The reaction mixture was directly purified by HPLC, providing 136. MS: 412.2 (M+1).
