YieldReaction ConditionsOperation in experiment
59% With acetic anhydride; at 100℃; for 1h; Compound 1-216[00431] Compound 1-216 was synthesized as described below. [00432] Stepl. Synthesis of 2-(l- 2-fluorobenz l)-5-(isoxazol-3-yl)-lH-pyrazol-3-yl)-5- (trifluoromethyl)-5,6-dihydropyrimidin-4(lH)-one: A mixture of D4 (from Example 7:General Procedure F) (where Rc = 3-isoxazolyl, and (JB)n = 2-fluoro) (500 mg, 1 equiv), 2- (trifluoromethyl)acrylic acid (218 mg, 1 equiv) and acetic anhydride (2.9 ml, 20 equiv) was heated to 100 C for 1 h. The mixture was concentrated under vacuum to give thick oil. The oil was purified by column chromatography to give 372 mg (59%) of 2-(l-(2-fluorobenzyl)- 5-(isoxazol-3-yl)-lH-pyrazol-3-yl)-5-(trifl^ JH NMR (400 MHz, CDC13) 8.87 (s, 1H), 8.45 (s, 1H), 7.11 (s, 1H), 7.04-6.92 (m, 3H), 6.60 (s, 1H), 5.87 (s, 2H), 4.12-3.99 (m, 2H), 3.29-3.25 (m, 1H).

YieldReaction ConditionsOperation in experiment
41% at 90℃; for 6h; A mixture of Intermediate-8C (1 equiv) and methyl 3-methoxyacrylate (3 equiv) was stirred at 90 °C for 6 h. The solvent was removed in vacuo and purification by silica gel chromatography (0-7percent methanol/dicloromethane) delivered the desired compound as a colorless solid (41percent).
