실험 절차

A solution of Example 26A (612 mg, 2.95 mmol) and (E)-3-(tert-butyldimethylsilyloxy)-N,N-dimethylbuta-1,3-dien-1-amine (966 mg, 4.25 mmol) in toluene (2.5 mL) was heated on a microwave at 60° C. for 30 minutes, and then 70° C. for 30 minutes. Purified by silica gel chromatography (AnaLogix® SF25-40G; 50 micron silica; elution with 0-50% ethyl acetate in hexane at 30 mL/min) to provide the title compound (787 mg, 1.81 mmol, 61.4% yield) as a light yellow oil. MS (DCI/NH3) m/e 435 (M+H)+.
