On the example of synthesis of 4-acetylamino-3-fluoroalkyl(aryl)-4,5,6,7-tetrahydro-1,2-benzisoxazoles, the effective approach to a synthesis of novel 4-acylamino-4,5,6,7-tetrahydro-1,2-benzisoxazoles is proposed. 3-Fluoroalkyl(aryl)- 6,7-dihydro-1,2-benzisoxazol-4-ones were reduced by a sodium borohydride in isopropanol to obtain 3-fluoroalkyl(aryl)- 4,5,6,7-tetrahydro-1,2-benzisoxazol-4-ols that in the conditions of the Ritter reaction (acetonitrile, acetic acid, sulfuric acid) gave target 4-acylamino derivatives with 80–94 % yields.
