The Soviets furnished formulas, speci- fications, production guidance, test procedures, and animal data. They may have also provided some precursor chemicals. The Czechs were working on aerosols as one method of applying the gaseous materials developed from this program. It is stated that LSD experiments had been disappointing but that other materials similar to LSD had been quite successful. The compounds were being developed to be dispersed over a wide area from the air. The agents were designed to make the population lose its will to resist for anywhere from two hours to two days, depending on the compound used and the nature of the mission. Damage would be limited to the brain (206). PART B - Piperidyl Benzilate and Piperidyl Glycolate 1. (U) In the course of the search for anticholinergic substances, it was found that methylpiperidyl benzilate and its derivatives are extremely active hallucinogens. If we start from the general formula for piperidyl benzilate and piperidyl glycolate, a series of highly active psychotropic compounds can be derived from it. The radicals of the formula below are involved as substituents. From the piperidyl benzilate series we can mention N-methylpiperidyl benzilate as a highly active psychotoxin (R1=CH3; R2 and R3=C6H5) .« From the piperidyl glycolate series, Ditran (R1= -C2H53; R2a= -C6l5; R3= -C5Hg) can be described as an extremely active compound.
