Reaction Steps

A solution of 1-(1,3-dimethyl-1H-pyrazol-4-yl)-8-(5-ethylamino-6-hydroxymethyl-pyridin-3-yl)-3-methyl-1,3-dihydro-imidazo[4,5-c]quinolin-2-one (Example 155.1, 0.086 mmol) in DMF (0.5 ml) was treated with 55% NaH in oil (0.086 mmol) and the RM was stirred for 10 min at rt, then was added iodomethane (0.086 mmol) and the RM was stirred for 2 h at rt. The RM was quenched with water, diluted with DMF, filtered and purified by preparative HPLC. The pure fractions were basified with NaHCO3, concentrated and extracted with CH2Cl2 (3×) and with EtOAc. The combined organic layers were dried over Na2SO4, filtered, evaporated and dried under vacuum to give the title compound as a film.
