Reaction Steps
A solution of compound 7b (6.1 g, 0.031 mol) and (5.1 g, 0.03 mol) compound 4a in MeOH (30 mL) was stirred for 15 min. Decaborane (1 g, 0.008 mol) was added and the reaction was stirred for 18 h. The solvent was evaporated in vacuo. The residue was used without further purification for the next step. MS m/z (M+H+) 353.1.
