実験手順

To 16.9 g of 2-amino 4-methoxy 5-pyrimidinyl carboxylic acid prepared in stage 2, in suspension in 300 ml of anhydrous ethyl ether, were added at 0° C., 20.8 g of phosphorous pentachloride while stirring. After returning to room temperature for 3 hours, the precipitate was separated by filtration, rinsed several times with 50 ml of absolute ethyl ether. The hydrochloride of the 2-amino 4-methoxy 5-chlorocarbonyl pyrimidine thus obtained was used in the raw state in the following stage.
