実験手順
In analogy to the procedure described for example 167A, 1-[(E)-3-(3,4-dichloro-phenyl)-acryloyl]-[1,4]diazepan-5-one (intermediate 1A]) and methanesulfonic acid 2-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethyl ester (prepared from 2-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethanol and methanesulfonyl chloride) gave after reaction at RT, the title compound as an off-white foam. MS: 441.1 (MH+, 2Cl).
