Participants

Reaction Steps

A suspension of Example 138 (132 mg) in 48% HBr (2 mL) and acetic acid (4 mL) was heated to 80° C. for 3 hours. The resulting homogeneous solution was concentrated and the residue was triturated from ethanol/diethyl ether to provide 130 mg of the desired product the dihydrobromide salt. 1H NMR (300 MHz, DMSO-d6) δ 3.67 (s, 2H), 6.95–6.98 (m, 6H), 7.34 (d, J=8.48 Hz, 2H), 7.51 (d, J=8.82 Hz, 2H), 7.85 (d, J=8.82 Hz, 2H), 9.83 (s, 1H); MS (ESI(+)) m/e 334 (M+H)+.
