FIELD: chemistry.
SUBSTANCE: method is realised by treating a compound of formula
with boronic acid or ether thereof of formula
,
in which two OR15 groups together with the boron atom with which they are bonded form a pinacolato boronate ester group in the presence of a Pd catalyst. The invention relates to a method of producing a pharmaceutically acceptable salt of thieno[3,2-d]pyrimidine of formula
.
The invention also relates to a pharmaceutical composition, having phosphatidyl inositol-3-kinase inhibitor activity, containing thieno[3,2-d]pyrimidine of formula (I) as an active ingredient, a method of preparing said composition and use of thieno[3,2-d]pyrimidine of formula (I) or pharmaceutically acceptable salt thereof in producing a medicinal agent for inhibiting phosphatidyl inositol-3-kinase.
EFFECT: use of the derivative as a phosphatidyl inositol-3-kinase inhibitor.
