Reaction Steps

Following the same procedure in Example 28 (Step C of Method B), using 1H-pyrazole-4-carbonyl chloride (0.47 g, 3.6 mmol), ethylamine (3.0 mL, 2.0 M in THF, 6.0 mmol) and triethylamine (1.01 g, 1.39 mL, 10 mmol) in CH2Cl2 (15 mL), provided the title compound as a white solid. Yield: 0.49 g (97% yield). 1H NMR (400 MHz, METHANOL-D4) δ 1.18 (t, J=7.23 Hz, 3 H) 3.34 (q, J=7.23 Hz, 2 H) 7.92 (s, 1 H) 8.09 (s, 1 H)
