Reaction Steps

to a round bottomed flask containing tert-butyl 1-(4-(1-(2-hydroxyethyl)-2-oxo-7-phenyl-2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazin-6-yl)phenyl)cyclobutylcarbamate (25 mg, 0.048 mmol) was added dichloromethane (2.5 ml) followed with hydrochloric acid (2.5 ml, 2M in diethyl ether). The resulting solution was stirred for 16 h. The precipitate was filtered and washed with ether (2×10 ml) and dried to afford the product (15.5 mg). 1H NMR (500 MHz, CH3OD) 7.78 (s, 1H), 7.42 (d, 2H), 7.38 (d, 2H), 7.30 (m, 3H), 7.22 (m, 2H), 4.96 (s, 2H), 4.16 (t, 2H), 3.86 (t, 2H), 2.73-2.79 (m, 2H), 2.54-2.60 (m, 2H), 2.21-2.26 (m, 1H), 1.94-1.99 (m, 1H). LCMS (Method D): RT=1.99 min, M+H+=416.2.
