Reaction Steps

The solution of tert-butyl 4-(3-((3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)carbamoyl)benzyl)piperazine-1-carboxylate (160 mg, 0.314 mmol) in DCM (2 mL) and TFA (2 mL) was stirred at 27° C. for 16 h. The solution was concentrated and the residue was purified by prep-HPLC to give the title product (89 mg, Yield 69.0%). 1H NMR (D2O, 400 MHz): δ 7.66-7.56 (m, 2H), 7.51-7.44 (m, 1H), 7.44-7.37 (m, 1H), 7.16-7.06 (m, 3H), 7.02 (d, J=7.3 Hz, 1H), 4.11 (quin, J=5.9 Hz, 1H), 3.73-3.60 (m, 2H), 3.56-3.49 (m, 2H), 3.49-3.42 (m, 1H), 3.41-3.32 (m, 1H), 2.86-2.75 (m, 8H), 2.68-2.58 (m, 2H), 2.56-2.32 (m, 4H). LCMS (m/z): 409.2 (M+1).
