Procedure: Using 5-chlorosalicylic acid and 3-acetylaniline as the raw materials, the same operation as the example 16 gave the title compound.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 3′-Aminoacetophenone (5 mmol, 0.7 g), 3-oxo-2-(2-oxo-2-phenyl-ethyl)-butyric acid ethyl ester (5 mmol, 1.2 g), and tosic acid (0.1 g) were combined in ethanol, then heated under reflux. The resulting oil was purified over silica and yielded the named product as a solid (m.p. 102° C.-104° C.). heated under reflux The resulting oil was purified over silica

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 3′-Amino-acetophenone (5 mmol, 0.7 g), 2-benzoyl-4-oxo-pentanoic acid ethyl ester (5 mmol, 1.2 g), and tosic acid (0.1 g) were combined in ethanol, then heated under reflux. The residual oil was purified over silica and yielded the named product (m.p. 100° C.-102° C.). heated under reflux The residual oil was purified over silica

Conditions: temp:140.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A neat mixture of 1,1-bismethylthio-2-nitroethylene (6.5 g, 38.5 mmol, 10 eq) and 3-aminoacetophenone (0.5 g, 3.85 mmol, 1 eq) was melted together and heated at 140° C. for four hours. The mixture was cooled to room temperature, then subjected to flash chromatography, eluting with 50% ethyl acetate/hexanes, to yield 0.63 g of a yellow powder as product. Yield=65%. NMR (300 MHz, CDCl3) δ 11.82 (bs, 1H), 7.95-7.91 (m, 2H), 7.59-7.48 (m, 2H), 6.73 (s, 1H), 2.65 (s, 3H), 2.41 (s, 3H). The mixture was cooled to room temperature eluting with 50% ethyl acetate/hexanes

Procedure: Compound No. 15 (CNI-1594): A suspension of m-aminoacetophenone (2.7 g) and 2-amino-4-chloro-6-methyl-pyrimidine (2.87 g) in 40 mL water was treated with 1.7 mL concentrated HCl and heated at reflux for 1 hour. Addition of 40 mL 1N KOH gave a light buff solid, which was filtered out and dried to give 3.8 g 4-(3-acetylphenyl)amino-2-amino-6-methylpyrimidine, mp 196-98° C. heated at reflux for 1 hour gave a light buff solid, which was filtered out dried
