Once the addition was complete, the mixture was heated to 50° C. for 3 hours. The mixture was then allowed to cool to room temperature and 3-methylthiopropanal (3.12 g, 30 mmole) was added. The reaction was stirred at room temperature for 1 hour. 2M ammonium chloride solution (50 mL) was added, followed by ether (50 mL). The organics were separated, dried, filtered, and evaporated to give a pale yellow oil that was purified by chromatography in 40-60 petroleum ether/ether (4/5) to give 5 (2.1 g, 36%) as a colorless oil.
