Tert-Butylamine → HCID 25234371, compound

Participants

Reaction Steps

To a biphasic mixture of 2,2-dimethyl-5-(phenylsulfonyl)-2,3,4,5-tetrahydrobenzo[b][1,4]thiazepine-7-carbonyl chloride (30 mg, 0.076 mmol) in DCM (2 mL) and saturated aqueous NaHCO3 (2 mL) was added tert-butylamine (25 μL, 0.236 mmol). The reaction was stirred at room temperature for 72 hours. TLC analysis of the reaction mixture indicated consumption of starting material. The biphasic mixture was extracted with DCM (3×2 mL). The combined organics were dried over Na2SO4 and concentrated in vacuo. The resulting solid was purified by flash column chromatography using a gradient elution of Hexanes with 5-50% EtOAc to provide N-tert-butyl-2,2-dimethyl-5-(phenylsulfonyl)-2,3,4,5-tetrahydrobenzo[b][1,4]thiazepine-7-carboxamide (26.3 mg, 0.052 mmol, 68.2% yield) as an off white solid. LCMS (+ESI) m/z=432.9 [M+H]+; 1H-NMR (CDCl3) δ 7.73-7.70 (m, 2H), 7.68-7.63 (m, 2H), 7.55 (tt, 1H), 7.49 (d, 1H), 7.47-7.41 (m, 2H), 5.89 (s, 1H), 3.77 (br s, 1H), 1.88 (br s, 2H), 1.46 (s, 9H), 1.12 (br s, 6H).
