Procedure

Compound 44 (21 mg, 0.025 mmol) was dissolved in CH2Cl2 (1.5 mL) and triethylsilane (10 uL, 0.063 mmol) and TFA (1.5 mL) were added. The solution was stirred for 2 hours at room temperature after which the solvents were evaporated and co-evaporated with toluene to provide compound 45 (20 mg, 100%) as a colorless solid.
