摘要：
Methods are provided for improving production of 3,5-diethyl-1,2-dihydro-1-phenyl-2-propylpyridine (DHP). In one illustrative embodiment, the methods involve controlling the rate of reaction and temperature of the reaction during formation of DHP. In another illustrative embodiment, the methods involve neutralizing the acid catalyst subsequent to DHP formation.
