4- (2¡¯,4¡¯-dinitrophenyl) -2,6-dimethyl-3,5-dicarbomethoxy 1,4-dihydropyridine After heating for several hours 9 g. 2,4-dinitrobenzalde hyde, 12 cc. acetoacetic acid methyl ester and 15 c ammonia, there are obtained pale brown crystals of M P 202¡ã C. to 205¡ã C. In an analogous manner there was obtained: from 2£¬4- dinitrobenzaldehyde, acetoacetic acid ethyl ester and am monia, 4- (2¡¯,4¡¯-dinitrophenyl) -2,6-dimethyl-3,5-dicarbeth oxy-1,4-dihydropyridine of M.P. 174¡ã C. to 176¡ã C. Fharmacology.¡ªThe following pharmacological data represents specific test results of 4-(2¡¯-nitrophenyl)-2 6 dimethyl-3,5-dicarbomethoxy-1,4-dihydropyridine (II) pro duced according to the process described in Example I or 4-(4¡¯-aminophenyl) -2,6-dimethyl-3,5-dicarbethoxy 1£¬4- dihydropyridine (I) produced according to the process ot Example 4. Other specific compounds of the present invention which were tested gave essentially the same re sults and these two compounds are, therefore, used as illustrative of the various species specifically disclosed in the generic invention as a whole. |
