Reaction Steps

The title compound was prepared from 8-chloro-4-[3-(2-hydroxymethyl-pyridin-4-yl)-phenyl]-7-methyl-1,3-dihydro-benzo[b][1,4]diazepin-2-one (Example 282) (196 mg, 0.50 mmol) by reaction with thionylchloride in CH2Cl2 and subsequent treatment of the corresponding crude chloride with sodium methanolate (5.4M, 1 ml) in MeOH (5 ml)/CH2Cl2 (5 ml) according to the general procedure of Example 288. Obtained as an off-white solid (72 mg, 35%).
