Reaction Steps

A mixture of 7-Chloro-2,5-dimethyl-3-(2,4,6-trimethyl-phenyl)-pyrazolo[1,5-a]pyrimidine (60 mg, 0.2 mmol) and 1-ethylpropylamine (4 ml) in 1 ml of N-methylpyrro-lidinone was heated at 125° C. oil bath for 15 hrs. The mixture was quenched with water and extracted with ethyl acetate. The organic layer was dried and concentrated and purified through silica gel column chromatography using 20% ethyl acetate in hexane as eluent to give 35 mg of the title compound as a yellow solid. 1H NMR (CDCl3) ä 6.96(s, 2H), 6.00(d, 1H), 5.77(s, 1)H, 3.47 (m, 1H), 2.43(s, 3H), 2.32(s, 3H), 2.22(s, 3H), 2.05(s, 6H), 1.5-1.9(m, 4H), 1.04(t, 6H) ppm.
