Participants

Reaction Steps

By the same method as in Example 59, 2,6-dihydroxy-pyrimidin-4-carboxylic acid (125 mg, 0.80 mmol), thionyl chloride (0.066 ml, 0.90 mmol), potassium carbonate (138 mg, 1.0 mmol) and 3,4-dihydro-2H-pyrido[4,3-b][1,4]oxazine (109 mg, 0.80 mmol) were reacted and the reaction mixture was purified in the same manner to obtain the target compound 60, i.e., (2,3-dihydro-pyrido[4,3-b][1,4]oxazin-4-yl)-(2,6-dihydroxy-pyrimidin-4-yl)-methanone, as white solid (32 mg, 15%).
