An aromatic compound K, whose molecular formula is C8H11N, is examined in the laboratory to elucidate its structure. The following observations were made:
A) Compound K is soluble in dilute hydrochloric acid but insoluble in sodium hydroxide solution.
B) Treatment of compound K with excess potassium hydroxide and benzenesulfonyl chloride, C(6)H(5)SO(2)Cl, results in the formation of a heterogeneous mixture. The NMR spectrum of compound K is shown below.
C) Compound K when treated with acetic anhydride[CH3-C(O)-O-C(O)-CH3], gives compound L, whose molecular formula is C(10)H(13)ON. Compound L is insoluble in dilute acid or dilute base at room temperature, heating compound L in dilute acid or base, however, regenerates compound K.
D) When compound L is heated with a mixture of concentrated nitric acid and sulfuric acid, a single product, compound M, with the molecular formula C(10)H(12)O(3)N(2) is formed in excellent yields.
On the basis of these observations draw the structures of…
