After stirring for 2 hours, diethylamine (1.0 mL, 9.7 mmol) (a compound of formula Y4)) was added. After stirring for 18 hours, the reaction was partitioned with ethyl acetate and water. The organic layer was separated, dried (Na2SO4), and the solvent was removed in vacuo to give 0.91 g of 2-[(2-cyanoethyl)[2-(1H-imidazol-1-yl)-6methyl-4-pyrimidinyl]amino)-N,N-diethylacetamide (a compound of formula (Yc3)).
