Reaction Steps

The title compound was prepared in a manner similar to that described in Example 49 step D from methyl 2-(tert-butoxy)-2-(6-methyl-4-(5-methylchroman-6-yl)-7-oxo-6,7-dihydro-1H-pyrrolo[2,3-c]pyridin-5-yl)acetate and 4-(bromomethyl)tetrahydro-2H-pyran, and was isolated as beige solid after reverse phase chromatography (45%): 1H NMR (400 MHz, CHLOROFORM-d) ppm 7.29 (d, J=8.6 Hz, 0.5H), 7.02-6.96 (m, 0.5H), 6.96-6.90 (m, 1H), 6.80-6.66 (m, 1H), 5.81-5.67 (m, 1H), 5.46-5.10 (m, 1H), 4.54-4.28 (m, 2H), 4.28-4.12 (m, 2H), 4.03-3.91 (m, 2H), 3.75-3.64 (m, 3H), 3.46-3.30 (m, 2H), 2.81-2.55 (m, 2H), 2.22 (d, J=3.7 Hz, 1H), 2.17-2.05 (m, 2H), 2.05-1.88 (m, 3H), 1.65-1.46 (m, 2H), 1.46-1.28 (m, 2H), 1.15 (s, 6H), 1.02 (s, 3H); LCMS (m/z) ES+=523 (M+1).
