実験手順: Isopropylamine (Aldrich; 1.5 ml, 17.62 mmol) and methyl acrylamide (ABCR; 1.0 g, 11.75 mmol) were combined in methanol (10 ml). The mixture was heated in a microwave at 140° C. for 30 min. The reaction was repeated and the combined reaction mixtures were concentrated to remove excess amine. The residue was re-dissolved in methanol and absorbed onto an SCX column (50 g), washed with methanol and eluted with ammonia/methanol. Concentration of the product containing fractions gave the title compound as a colourless oil (3.2 g, 94%). the combined reaction mixtures were concentrated to remove excess amine The residue was re-dissolved in methanol absorbed onto an SCX column (50 g) washed with methanol eluted with ammonia/methanol Concentration of the product containing fractions

実験手順: N-Methylacrylamide (851 mg, 10.00 mmol) and isopropylamine (1.71 mL, 1.18 g, 20.00 mmol) in MeOH (10 mL) were irradiated to 140° C. for 30 mins in a microwave reaction vessel. The reaction mixture was cooled and loaded onto a SCX-2 column and washed with MeOH (100 mL). The crude product was then eluted from the SCX-2 column with NH3 (100 mL, 7M in MeOH) and the volatiles removed under reduced pressure to afford the title compound (1.56 g, Quant.) as an oil, which was used without further purification. The reaction mixture was cooled washed with MeOH (100 mL) The crude product was then eluted from the SCX-2 column with NH3 (100 mL, 7M in MeOH) the volatiles removed under reduced pressure

実験手順: 5-Bromo-2,4-dichloropyrimidine (1.83 g, 8.00 mmol), N-methyl-3-(propan-2-ylamino)propanamide (Intermediate 14, 1.16 g, 8.00 mmol) and Et3N (1.2 mL, 8.16 mmol) were combined in MeCN (50 mL) and shaken at ambient temperature for 3 days before the solvent was removed under reduced pressure. Purification by column chromatography (SiO2, eluent gradient 2-10% MeOH to DCM) to afford the title compound (2.08 g, 78%) as a gum. was removed under reduced pressure Purification by column chromatography (SiO2, eluent gradient 2-10% MeOH to DCM)
