Reaction Steps

4-(8-methoxy-1-(1-methoxypropan-2-yl)-2-(tetrahydro-2H-pyran-4-yl)-1H-imidazo[4,5-c]quinolin-7-yl)-3,5-dimethylisoxazole (85 mg) was dissolved in ethanol (ca. 4 ml) with heating and sonication. Injections (400 μl) were then made via plastic syringe. The fractions between 24 min and 26.5 min were collected and the combined fraction solutions were evaporated to dryness using a rotary evaporator (30° C. bath temp). The residue was transferred to a tared glass vial using ethanol (ca 12 ml). The solvent was then removed by evaporation under a stream of nitrogen gas (room temp) to give 4-(8-methoxy-1-((S)-1-methoxypropan-2-yl)-2-(tetrahydro-2H-pyran-4-yl)-1H-imidazo[4,5-c]quinolin-7-yl)-3,5-dimethylisoxazole (38 mg).
