To a solution of tert-butyl 2-(8-(benzo[d]thiazol-2-yl((2-(trimethylsilyl)ethoxy)methyl)carbamoyl)-3,4-dihydroisoquinolin-2(1H)-yl)-5-(3-hydroxypropyl)thiazole-4-carboxylate (38E) (68 mg, 0.1 mmol) in DCM (2 mL) was added 2 mL of 2N HCl in ether. The mixture was stirred at rt overnight. MeOH (0.5 mL) was added to the mixture to dissolve the solid. The mixture was stirred at rt for another 2 hours. The reaction mixture was concentrated under reduced pressure to provide the desired product as an HCl salt: 1H NMR (300 MHz, DMSO-D6) δ ppm 8.03 (1H, d), 7.79 (1H, d), 7.67 (1H, d), 7.41 (5H, m), 4.83 (2H, s), 3.73 (4H, t), 3.50 (2H, t), 3.41 (2H, t), 3.04 (4H, t), 1.69 (2H, m). MS (ESI(+)): m/z 495 (M+H).
