Reaction Steps

A solution of Intermediate 62b (615 mg, 2.31 mmol) and imidazole (189 mg, 2.78 mmol) in DMF (4.5 mL) was added tert-butyl dimethylchlorosilane (384 mg, 2.55 mmol). The solution was stirred for 2 h then added tert-butyl dimethylchlorosilane (192 mg, 1.28 mmol). After 1.5 h, the solution was diluted with water and extracted with EtOAc. The combined organics were dried and concentrated in vacuo to give the title compound (831 mg, 94%). LCMS (Method 3): Rt 5.21 min, m/z 380 [MH+].
