実験手順

A mixture of 2-(4-((S)-3-(aminomethyl)pyrrolidin-1-yl)-7-methylquinazolin-2-yl)phenol (200 mg, 0.6 mmol), THF (6.0 mL), and DMF (1 mL) was stirred under an N2 atmosphere. Triethylamine (0.166 mL, 1.2 mmol) was added, and the reaction was cooled in an ice bath. To this was added 1 M neopentyl chloroformate solution (89 μL in 600 μL THF, 0.6 mmol). After allowing the reaction mixture to warm to room temperature over a period of 30 minutes, CH2Cl2 was added to the reaction mixture, and it was washed once with water before it was dried over Na2SO4, filtered, and concentrated. Purification via silica gel chromatography using 0-20% EtOAc in CH2Cl2/hexanes (1:1) gave neopentyl((S)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)pyrrolidin-3-yl)methylcarbamate (222 mg, 94%). LC/MS: m/z 449 (M+H)+ at 2.73 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)). 1H NMR (400 MHz, acetic acid-d4) δ 8.42 (dd, J=8.1, 1.8 Hz, 1H), 8.20 (d, J=8.7 Hz, 1H), 7.57 (s, 1H), 7.40-7.29 (m, 3H), 6.92-6.89 (m, 2H), 4.11-3.92 (m, 3H), 3.78-3.61 (m, 3H), 3.33-3.28 (m, 1H), 3.23-3.10 (m, 2H), 2.49 (s, 3H), 2.16-2.08 (m, 1H), 1.83-1.75 (m, 1H), 0.89 (s, 9H).
