An amino acid may be represented by general formula `H_(2)N overset(R)overset(|)(CH)-COOH`. If `R = -CH_(2)C_(6)H_(5)` then it is phenylalanine (Phe) and if `R = CH_(3)` then it is alanine (Ala). Find the sequence of reagents from those given below to synthesize Phe-Ala.
(1) `ZNHoverset(CH_(3))overset(|)(CH)CO_(2)H` , (2) `H_(2)N overset(CH_(3))overset(|)(CH)CO_(2)CH_(2)C_(6)H_(5)`
(3) `ZNHoverset(CH_(2)C_(6)H_(5))overset(|)(CH)CO_(2)H`
(4) `H_(2)N overset(CH_(2)C_(6)H_(5))overset(|)(CH)CO_(2)CH_(2)C_(6)H_(5)`
