Reaction Conditions

Reaction Steps

To a 0° C. solution of 4-[(t-butoxycarbonyl)-amino]-4-phenylbutanol (133 mg, 0.5 mmol) in dichloromethane (8 mL) was added triethylamine (0.140 mL, 1.0 mmol), followed by methanesulfonylchloride (0.057 mL, 0.75 mmol). The solution was then stirred at 0° C. for 15 minutes before being quenched with an aqueous ammonium chloride solution (2 mL). The aqueous and organic layers were then separated, the aqueous layer extracted twice with dichloromethane, and the combined organic fractions were dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to afford 4-[(t-butoxycarbonyl)-amino]-4-phenylbutanol mesylate as a yellow oil, which was used immediately in the next reaction without further purification. 1H NMR (CDCl3) δ 1.43 (s, 9H), 1.67-2.00 (m, 4H), 2.95 (s, 3H), 4.18 (t, 2H, J=7.1 Hz), 4.20 (m, 1H), 4.92 (br s, 1H(NH)), 7.21-7.33 (m, 5H).
