Reaction Steps
Compound 113 (530 mg, 1.8 mmol) was dissolved in dry DMF (17 mL) under N2.Zn(CN)2 (416 mg, 3.6 mmol) and Pd(PPh3)4 (200 mg, 0.18 mmol) was added. The reaction mixture was stirred and heated at 150° C. in a microwave instrument (CEM Discover®) for 20 min and the reaction mixture was then concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with EtOAc/hexanes (20˜80%) to yield 114 (540 mg, 31%) as a white solid. MS (APCI, negative): m/z 245 [M−H]+.
