Reaction Steps

A solution of 1,3-bis(tert-butoxy-carbonyl-[3-bromo-4-(3-fluoro-propoxy)-benzyl]-guanidine (250.6 mg, 50 mmol) in 4N HCl in dioxane (6 mL) was heated to 50° C. for 2 h. The reaction mixture was diluted with water (4 mL) and ACN (1 mL) and lyophilized to afford N-[3-bromo-4-(3-fluoro-propoxy)-benzyl]-guanidine hydrochloride as a white solid (169.1 mg, 99% yield). 1H NMR (DMSO-d6, 600 MHz): δ 8.03 (br t, 1H), 7.55 (m, 1H), 7.31-7.27 (m, 2H), 7.15 (d, J=9 Hz, 1H), 4.72 (t, J=6 Hz, 1H), 4.56 (t, J=6 Hz, 1H), 4.30 (m, 2H), 4.15 (t, J=6 Hz, 2H), 2.19-2.06 (m, 2h).
