Reaction Steps

A solution of the carbamate (7) (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 and then purified by flash column chromatography (SiO2, 4 g, 0-100% EtOAc in MeOH, gradient elution) to afford the title compound (Example 9) as an off-white solid (13 mg, 57%): m/z 606 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.20 (3H, d), 1.27 (9H, s), 2.26 (3H, s), 2.39 (3H, s), 3.20 (1H, q), 5.38 (2H, s), 6.35 (1H, s), 7.01 (1H, d), 7.28 (1H, dd), 7.36 (2H, m), 7.44 (2H, m), 7.55-7.63 (3H, overlapping m), 7.93 (1H, m), 8.31 (1H, m), 8.34 (1H, dd), 8.36 (1H, br s), 8.60 (1H, s), 8.80 (1H, s).
