Reaction Steps

A solution of the carbamate (6) (25 mg, 0.04 mmol) in DCM/TFA (1:1 v/v, 2.0 mL) was stirred at RT for 30 min. The reaction mixture was evaporated in vacuo and the resulting residue was subjected to SCX capture and release to afford the title compound (Example 8) as a pale brown solid (20 mg, 89%): m/z 620 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.25 (6H, s), 1.27 (9H, s), 2.20 (3H, s), 2.39 (3H, s), 5.38 (2H, s), 6.35 (1H, s), 7.00 (1H, d), 7.27 (1H, dd), 7.36 (2H, m), 7.44 (2H, m), 7.58-7.62 (3H, overlapping m), 7.93 (1H, m), 8.29-8.34 (3H, overlapping m), 8.59 (1H, br s), 8.79 (1H, br s).
