1 more element
A process for producing a compound having a formula (4) comprising the steps of:
- (i) reacting [4-(4-pyridyl)-1,3-thiazol-2-yl]thiol with an acylating agent to provide a compound having the formula (ii)
- wherein R is R1—C(O)— with R1 being C1-12 alkyl or R2—O—C(O)— with R2 being C1-4 alkyl, benzyl or phenyl;
- and
- (ii) reacting the resultant compound having the formula (ii) with a methylating agent to provide the compound having the formula (4)
1 more element
