Reaction Steps

Following the procedure used to prepare 3-(4-(1-aminocyclobutyl)phenyl)-2-phenyl-8-(1,3,5-trimethyl-1H-pyrazol-4-yl)-4H-pyrano[2,3-c]pyridin-4-one, tert-butyl (1-(4-(4-oxo-2,8-diphenyl-4H-pyrano[2,3-c]pyridin-3-yl)phenyl)cyclobutyl)carbamate was reacted give the title compound (5 mg, 15%). 1H NMR (500 MHz, CD3OD): δ 8.65 (d, J=5.1 Hz, 1H), 7.96 (d, J=5.1 Hz, 1H), 7.89-7.85 (m, 2H), 7.46-7.15 (m, 12H), 2.69-2.63 (m, 2H), 2.49-2.52 (m, 2H), 2.20-2.11 (m, 1H), 1.92-1.78 (m, 1H). LCMS (Method I): RT=4.67 min, [M+2]+=446.
