Reaction Steps

Solid supported cyanoborohydride (2.5 mmol/g, 46 mg) was added to a solution of 4-fluoro-N-[2-fluoro-5-(1-trityl-1H-benzotriazol-5-yl)-benzyl]-N-piperidin-4-yl-benzamide (20 mg, 0.029 mmol), (1-ethoxy-cyclopropoxy)-trimethylsilane (25 mg, 0.145 mmol) and acetic acid (1.74 mg, 0.029 mmol) in 1 mL of methanol. The mixture was stirred at 45° C. for 2 h and then at 75° C. overnight. The mixture was cooled and filtered and the filtrate concentrated in vacuo to provide the crude product. Chromatography provided 14 mg of product. LC/MS: Retention time, 3.20 min; (M+H)=730.
