The resulting yellow mixture was then refluxed for 1 hour during which it gradually became cloudy. After addition of a further 7.2 g of the 30% strength solution of sodium methanolate in methanol (0.04 mol of sodium methanolate), the mixture was refluxed for a further 30 minutes and, after cooling to 20° to 25° C., diluted with 150 ml of water and neutralized with 1 normal aqueous hydrochloric acid. The solvent was then removed at 40° C. under reduced pressure, after which the resulting solid was separated off and dried at 40° C. under reduced pressure for 15 hours.
