Reaction Steps

(R)-2-hydroxy-1-(4-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperazin-1-yl)-4-methylpentan-1-one (90 mg, 0.20 mmol) was dissolved in 1 mL CH2Cl2 and treated with 1 equivalent of 2.0 M HCl in ether (100 μL, 0.20 mmol). The formed precipitate was filtered and vacuum dried to obtain (R)-2-hydroxy-1-(4-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperazin-1-yl)-4-methylpentan-1-one hydrochloride. LC/MS: m/z 435.1 (M+H)+ at 2.84 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)). 1H NMR (400 MHz, CD 30D) δ 8.39-8.37 (m, 1H), 8.18 (d, J=8.6 Hz, 1H), 7.78 (s, 1H), 7.61-7.55 (m, 2H), 7.15-7.11 (m, 2H), 4.57 (dd, J=9.5, 3.5 Hz, 1H), 4.49-4.32 (m, 4H), 4.07-3.79 (m, 4H), 2.62 (s, 3H), 1.97-1.87 (m, 1H), 1.65-1.58 (m, 1H), 1.53-1.47 (m, 1H), 1.03-1.00 (m, 6H) ppm.
