Ethyl methylamine

B is correct. This is a simple alkylation of an amine. You should have this reaction memorized. Even if you don t, only B and D are possibilities for a base. Ethyl-methylamine is not an acid. 

Meperidine hydrochloride (the full name) is a synthetic opioid. It is synthesized by the reaction of chemicals not found in opium. Specifically, meperidine hydrochloride is produced by the reaction of dichlorodi-ethyl methylamine with benzyl cyanide, to produce ethyl l-methyl-4-phenyl-isonipecotate hydrochloride (meperidine s chemical name). Some references to meperidine classify it as a totally synthetic opioid. Semi-synthetic opioids are produced by using one of the opiates as a starting material. Two examples of semi-synthetic opioids are hydrocodone and heroin. Hydrocodone is produced by the chemical modification of codeine, while heroin is made by chemically altering morphine.

The amide of bis(2-thienyl)glycolic acid with 2-(lV-pyrrolidyl)ethyl-methylamine and its methyl quaternary ammonium hydroxide showed spasmolytic activity in mice.155 Esters of 3,3-bis(2-thienyl)propenoic acid and 2-ferf-aminoethanols 99 (X = OCH2CH2NR2) were obtained both by dehydration of the hydroxy ester 100 (X = OCH2CH2NR2)156 and by esterification of unsaturated acid 99 (X = OH).157 These amino esters showed analgesic, antispasmodic, and antitussive activity. Amides 99 (X = NHAr) were synthesized by reaction of the appropriate primary aromatic...
