2-Aminopyridine-3-carboxamide → 2-(2-m-Tolyl-ethoxymethyl)-3H-pyrido[2,3-d]pyrimidin-4-one

Participants

Reaction Steps

In analogy to example 91.3, 2-amino-nicotinamide and (2-m-tolyl-ethoxy)-acetic acid methyl ester (prepared from 2-m-tolyl-ethanol [1875-89-4] in analogy to example 91.1-91.2) reacted in the presence of LiHMDS in THF to yield after purification of the crude product with column chromatography (silica gel, EtOAc) and crystallization from EtOAc/heptane 2-(2-m-tolyl-ethoxymethyl)-3H-pyrido[2,3-d]pyrimidin-4-one as white solid. MS (m/e): 296.4 [M+H+].
