Procedure

To the light brown crude oil from Step 2 was added DCM (3 ml) and TFA (1 ml) and the mixture stirred at room temperature for 30 min affording PMB deprotection. The mixture was dried under reduced pressure and purified using basic, then acidic conditions, respectively affording product (16 mg, 16%). 1H NMR (400 MHz, DMSO-d6) δ=12.91 (br. s., 1H), 8.69 (d, J=5.8 Hz, 1H), 8.56 (d, J=1.9 Hz, 1H), 8.14 (d, J=5.2 Hz, 1H), 7.86 (dd, J=1.9, 8.9 Hz, 1H), 7.71 (d, J=8.9 Hz, 1H), 7.54 (d, J=1.9 Hz, 1H), 7.45 (d, J=8.1 Hz, 1H), 7.34 (dd, J=1.9, 8.1 Hz, 1H), 7.28 (d, J=4.6 Hz, 1H), 6.87 (d, J=4.6 Hz, 1H), 5.16 (d, J=1.0 Hz, 2H). m/z (ESI) 457.0 (M+H)+
