Reaction Steps

A mixture of Intermediate 55fB (100 mg, 0.11 mmol) and dimethylamine (2.0M in THF, 0.80 mL, 1.60 mmol) in THF (3 mL) was stirred at 60° C. for 18 h in a sealed vial. The volatiles were concentrated in vacuo and the residue was used in the next step without further purification (94 mg, 100%). LCMS (Method 3): Rt 3.75 min, m/z 893 [MH+].
