Reaction Steps

5-Ethyl-2-(phenylethynyl)pyrimdine (730 mg, 3.7 mmol) was dissolved in CH2Cl2 (3.0 mL) and treated with HCl in diethyl ether (4.1 mL of a 1N solution, 4.1 mmol). Upon addition of the HC1 solution a solid precipitated from the solution. The mixture was diluted with diethyl ether (2 mL) and the supernatant decanted. The resultant solid was dried under high vacuum at 50° C. to afford 5-ethyl-2-(phenylethynyl)pyrimdine hydrochloride (450 mg, 49% yield) as an orange solid. M.p. 101-104° C. 1H NMR (CD3OD, 300 MHz) Δ8.75 (s, 2H), 7.58-7.55 (m, 2H), 7.41-7.32 (m, 3H), 2.67 (q, J=7.6 Hz, 2H), 1.21 (t, J=7.6 Hz, 3H).
