Reaction Steps

To a solution of (S)-5-(4-chloro-3-(5-phenyl-1H-imidazol-2-yl)phenylamino)-2-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-3,4-dihydroisoquinolin-1(2H)-one (210 mg, 0.40 mmol) in THF (1.6 ml) and water (0.4 ml) is added TFA (0.1 ml) at room temperature, and the reaction mixture is stirred for 18 hours. The reaction mixture is concentrated to dryness by rotary evaporation and the crude product is purified by preparative HPLC to afford (S)-5-(4-Chloro-3-(5-phenyl-1H-imidazol-2-yl)phenylamino)-2-(2,3-dihydroxypropyl)-3,4-dihydroisoquinolin-1(2H)-one as an off-white solid. LC-MS m/z: 489.1 (M+1); 1H NMR 400 MHz (CDCl3) δ 7.76 (d, 1H, J=7.6 Hz), 7.67-7.63 (m, 3H), 7.40-7.32 (m, 4H), 7.27-7.20 (m, 3H), 6.71-6.68 (m, 1H), 3.89-3.87 (m, 1H), 3.66-3.53 (m, 6H), 2.82 (t, 2H, J=6.8 Hz).
