Reaction Steps

Under nitrogen, a solution of (2S)-1-[N-benzyl-(3-benzyloxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amino]-3-phenoxy-2-propanol (20 g), chlorotriethylsilane (7.4 ml), imidazole (3.2 g) and 4-dimethylaminopyridine (0.48 g) in N,N-dimethylformamide (200 ml) was stirred at room temperature for 12 hours. The resulting mixture was poured into water, and extracted with ethyl acetate-hexane (1:1). The organic layer was successively washed with saturated aqueous sodium hydrogencarbonate and brine, dried over anhydrous magnesium sulfate, and evaporated in vacuo to give N-benzyl-N-(3-benzyloxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-[(2S)-3-phenoxy-2-(triethylsilyloxy)-propyl]amine (25 g).
