How about this sequence?

Explanation:

CH3CH2CH2Bralcoholic KOHX−−−−−−−−−→CH3CH=CH2HBrX−−−→(CH3)2CHBr

CH3CH=CH21. O3; 2. Zn/HOAcX−−−−−−−−−−−→CH2O

(CH3)2CHBrMg, dry etherX−−−−−−−−→(CH3)2CHMgBr1. CH2O; 2. H+X−−−−−−−−−→(CH3)2CHCH2OH

(CH3)2CHCH2OHPBr3X−−−→(CH3)2CHCH2Br

(CH3)2CHCH2BrNaSHX−−−→(CH3)2CHCH2SHNaHX−−−→(CH3)2CHCH2S−

(CH3)2CHCH2S−CH3CH2CH2BrX−−−−−−−−−→(CH3)2CHCH2SCH2CH2CH3
