(Synthesis of X-4) In a three-neck flask, after filling the inside of flask with nitrogen gas, 6.5 g of 10% Pd-C (produced by Wako Pure Chemical Industries, Ltd.) was added, and 2,000 mL of ethanol and the entire amount of the crude product of Compound (X-3) obtained above were further added. The resulting mixture was heated/refluxed, and 55 mL (3 molar equivalents) of formic acid was slowly added dropwise thereto, followed by stirring at this temperature for 5 hours. The resulting reaction mixture was cooled to an inner temperature of 25C and then subjected to Celite filtration and to the mother solution separated by filtration, 105 g of 1,5-naphthalenedisulfonic acid was added. After raising the inner temperature to 70C, the mixture was stirred for 30 minutes and then gradually cooled to room temperature, and the crystal was separated by filtration to obtain 100 g of Compound (X-4). The yield was 72% based on Compound (X-1) as the starting material. The obtained crystal was pale brown. 1H NMR (deuterated DMSO): delta6.95-6.98 (1H), delta7.02-7.04 (1H), delta7.40-7.51 (3H), delta7.90-7.95 (1H), delta8.75 (1H), delta8.85-8.88 (2H), delta9.03 (2H), delta10.89 (1H).
36216-80-5 Benzo[d]isoxazol-3-amine 2779749, aBenzisoxazole compound, is more and more widely used in various.
