Abstract: The invention provides a more handy and environment friendly process for preparing risperidone, which comprises reacting 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole hydrochloride with 3-(2-chloroethyl)-2-methyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one in a basic aqueous solution or suspension. The concentration of alkaline metal carbonates in the basic aqueous solution or suspension is ranged from 15% to 40%. The reaction is carried out at a temperature range of 101-140° C. and the reaction is completed within 10 minutes to 2 hours.
