Reaction Steps

To a solution of sodium ethoxide in ethanol (made by addition of sodium (0.155 g, 6.7 mmol) to dry ethanol(15 ml)) was added methyl iodide (1.47 ml, 23.6 mmol) followed by N-carbethoxythiourea (1.0 g, 6.7 mmol). The resulting solution was stirred at 21° C. under nitrogen for 1 hr. This was then treated with ether (32 ml) and the resultant precipitate filtered off. The filtrate was evaporated to a clear syrup, which crystallised at 0-4° C. to give the title compound as a white solid (0.815 g).
