실험 절차

A mixture of 2-chloro-6-(6-fluoropyridin-3-yl)-4-morpholinothieno[3,2-d]pyrimidine or 2-chloro-6-(6-fluoropyridin-3-yl)-4-morpholinothieno[2,3-d]pyrimidine compound, about four equivalents of a primary or secondary amine (R=H, C1-C12 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C3-C12 carbocyclyl, C2-C20 heterocyclyl, C6-C20 aryl, or C1-C20 heteroaryl), and about two eq. diisopropylethylamine in N-methylpyrrolidine (a 0.1M) is heated to about 130-140° C. in a sealed microwave reactor for 10-40 min, followed by removal of volatiles under high vacuum. The crude mixture is purified by flash chromatography to give intermediate 2-chloro-6-(6-aminopyridin-3-yl)-4-morpholinothieno[3,2-d]pyrimidine or 2-chloro-6-(6-aminopyridin-3-yl)-4-morpholinothieno[2,3-d]pyrimidine compound, which may be Suzuki coupled with a monocyclic heteroaryl, fused bicyclic heterocycle or heteroaryl boronate reagent following General Procedure A.
