Benzyl Bromide → HCID 58017458, compound

Participants

Reaction Steps

N-(3 Methoxyphenylsulfonyl)D-tert-leucine (3.03 g, 10.1 mmol) is dissolved in DMF (30 ml). Potassium Carbonate (2.81 g, 20.1 mmol) is added followed by Benzyl Bromide (1.21 ml, 9.95 mmol) and the reaction is stirred at ambient temperature for 18 hours. The reaction mixture is partitioned between Ethyl Acetate and 1 N HCl. The organics are separated and washed with brine, dried over MgSO4 and concentrated. The residue is purified by column chromatography eluting with a gradient of 5-60% (Hex-EtOAc) to give the title compound (3.08 g, 78% yield). Mass spectrum (392.2; M+1, 390.2; M−1).
