Reaction Steps

To a solution of carbonic acid 7-tert-butoxycarbonylamino-8,8-diethyl-trans-6-mercapto-5,6,7,8-tetrahydro-naphthalen-2-yl ester tert-butyl ester (28.2 mg, 0.062 mmol) in acetone (2 mL) was added the iodomethane (20 μL, 0.31 mmol) and the potassium carbonate (26 mg, 0.18 mmol), and stirred at reflux for 4 h. The mixture was quenched with H2O, diluted with Et2O (50 mL), washed with H2O, brine, dried over MgSO4. The residu was purified by a flash chromatography (10% AcOEt/Hex) (21.2 mg , 73%). 1H NMR (CDCl3): 7.08 (1H, d, J=8.5 Hz, H5), 7.00-6.95 (2H, m, H6 and H8), 4.56 (1H, d, J=11 Hz, NH), 4.09 (1H, t, J=11.0 Hz, CHNH), 3.25-3.00 (3H, m), 2.15 (3H , broad, SCH3), 1.76 (4H, m, CH2), 1.57 (9H, s, t-butyl), 1.50 (9H, s, t-butyl), 0.73 (6H, m, CH3).
