Reaction Steps

A solution of the carbamate (8) (28 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 capture and release on SCX and then triturated from diethyl ether (10 mL) to afford the title compound (Example 10) as an off-white solid (13 mg, 53%): 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), 6.35 (1H, s), 7.00 (1H, d), 7.29 (1H, dd), 7.36 (2H, m), 7.44 (2H, m), 7.58-7.62 (3H, overlapping m), 7.92 (1H, m), 8.28-8.35 (3H, overlapping m), 8.58 (1H, br s), 8.79 (1H, br s), 10.09 (1H, br s) [partial assignment].
