Reaction Steps

A solution of the carbamate (9) (30 mg, 0.04 mmol) in DCM/TFA (1:1 v/v, 2.0 mL) was stirred at RT for 1 hr and was then evaporated in vacuo. the resulting residue was subjected to capture and release on SCX and then triturated from DCM (5.0 mL) and isohexane (5.0 mL) to afford the title compound (Example 11) as a brown solid (15 mg, 63%): m/z 634 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.26 (9H, s), 2.39 (3H, s), 2.73-2.92 (3H, overlapping m), 3.56-3.64 (4H, overlapping m), 3.82 (1H, m), 5.38 (2H, s), 6.34 (1H, s), 7.00 (1H, d), 7.29 (1H, dd), 7.35 (2H, m), 7.42 (2H, m), 7.55-7.62 (3H, overlapping m), 7.91 (1H, m), 8.30 (1H, dd), 8.32 (1H, br s), 8.35 (1H, dd), 8.56 (1H, br s), 8.77 (1H, br s) 10.16 (1H, br s).
