In contrast to previous reports in the literature, it has been shown that both 1- and 3-carbethoxyindole are obtained from the reaction of indole magnesium iodide with 1 or 2 moles of ethyl chloroformate. The formation of 1-carbethoxyindole was favored at low temperatures (i.e. −10°), whereas maximum yields of 3-carbethoxyindole were obtained at 10°. Significant quantities of 1,3-dicarbethoxyindole are only formed in the presence of 2 equivalents of ethyl chloroformate and when the reaction is carried out at higher temperatures (i.e. 35°).Paper and gas–liquid chromatographic systems have been developed for the qualitative and quantitative analysis of mixtures containing indole, 1-, 2-, and 3-carbethoxyindole, and 1,3-dicarbethoxyindole.

Experimental Process

Attitudes towards tax compliance (willingness to comply) Indonesian society is still low. Required an innovative tax dissemination to increase it. The purpose of this study was to determine whether the tax dissemination based on Fogg Behavioral Model (FBM) approach may increase wiliingness to comply. The FBM based tax dissemination asserts that for a person to perform a target behavior, which is a willingness to comply, he or she must be sufficiently motivated, have the ability to perform the behavior, and be trigerred, to perform the behavior. This research is a combination of qualitative and quantitative analysis of statistical data results of the questionnaire, interviews, and observations of the respondent and the experimental process of dissemination. The method used in this study is a quasi experimental with patterns of nonequivalent control group (pretest-post which is not equivalent). Based on the results of data analysis, interviews and observations of the respondent and the experiment, this research showed that theFBMbasedtaxdissemination hasapositiveimpactto willingnesstocomplyofthetaxpayers.
