Paul writes 1 Timothy and Titus
1 Timothy 1:3; 3:14–15; Titus 1:5
After his release, Paul left Timothy to lead the church at Ephesus and Titus to set things in order on Crete, and wrote to guide them: sound teaching, qualified elders, godly living, and the grace that saves.
The saying is faithful and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief.
1 Timothy 1:15 (World English Bible)
These letters, with 2 Timothy, are called the Pastoral Letters. They describe travels that don't fit the story of Acts, which supports the early tradition that Paul was released from his first Roman imprisonment.

About AD 62–64, between Paul's two Roman imprisonments. Ussher dates 1 Timothy to AD 65. Many modern scholars doubt Paul wrote the Pastoral Letters; the letters name him as author, and the early church accepted them as his. The date is an estimate; Scripture doesn't say when the book was written.
